  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  First, a vehicle 11 provided with an imaging device 10 according to a first embodiment of the present invention will be described with reference to FIG. The vehicle 11 includes an imaging device 10 and a display device 12. The vehicle 11 includes an in-vehicle network such as CAN. In the present embodiment, the vehicle 11 includes one imaging device 10, but may include any number of imaging devices 10.

  The imaging device 10 is installed in the vehicle 11 so that, for example, a rear peripheral region of the vehicle 11 can be imaged. The imaging device 10 is connected to an in-vehicle network. The imaging device 10 outputs the generated captured image to the display device 12 through, for example, a dedicated line.

  The display device 12 is, for example, a liquid crystal display or an organic EL display, and is installed at a position on the vehicle 11 that is visible to the driver of the vehicle 11. The display device 12 displays a captured image acquired from the imaging device 10 via a dedicated line. By visually recognizing the captured image displayed on the display device 12, the driver can recognize the state behind the vehicle 11 when the vehicle 11 is parked, for example.

  Next, the motion analysis system 13 including the imaging device 10 according to the present embodiment will be described with reference to FIG. As an outline, the operation analysis system 13 is used for operation confirmation work and debugging work of the imaging apparatus 10.

  The motion analysis system 13 includes an imaging device 10 and an information processing device 14. The information processing apparatus 14 is connected to the in-vehicle network 15 when, for example, performing an operation check work and a debug work of the imaging apparatus 10. Hereinafter, each component of the motion analysis system 13 will be specifically described.

  The imaging device 10 includes an optical system 16, an imaging element 17, an AFE 18, a communication unit 19, a storage unit 20, and a processing unit 21.

  The optical system 16 includes a stop and a plurality of lenses, and forms a subject image. In the present embodiment, the optical system 16 has a wide angle of view, and can form, for example, a subject image in the peripheral region of the vehicle 11 or a subject image in the vehicle 11.

  The image sensor 17 is a CMOS image sensor, for example, and images an object image formed by the optical system 16 to generate an analog captured image. Here, since the optical system 16 has a wide angle of view as described above, the image pickup device 17 can generate a picked-up image taken at a wide angle.

  The AFE 18 includes, for example, CDS, AGC, and ADC. The AFE 18 performs predetermined pre-stage image processing such as CDS, gain adjustment (AGC), and A / D conversion (ADC) on the analog captured image generated by the image sensor 17.

  The communication unit 19 is an interface that inputs and outputs information via the dedicated line 22 and the in-vehicle network 15.

  The storage unit 20 is, for example, a memory, and stores various information and various programs necessary for the operation of the imaging apparatus 10.

  Here, with reference to FIG. 3, among the various programs stored in the storage unit 20, the program 23 according to the present embodiment will be specifically described. For example, the program 23 is divided into a plurality of blocks for each function to be executed by the imaging apparatus 10. Each block is associated with a block ID that can uniquely identify each block.

  In the present embodiment, a predetermined command statement (hereinafter referred to as history generation code) 24 for generating history information of processing of the program 23 by the processing unit 21 is inserted into the program 23 at an arbitrary location. History information is generated by processing the history generation code 24.

  Specifically, for example, when the history generation code 24 is described as “tool_print (time, processing location ID, importance, block ID, variable a, variable b)”, the history generation code 24 is processed. , History information including time, processing location ID, importance, block ID, value of variable a, and value of variable b is generated. The description of the history generation code 24 and the information included in the history information are not limited to those described above.

  The time is information indicating the time when the history generation code 24 is processed.

  The processing location ID is information indicating the location where the processing is executed in the program 23, that is, the position of the history generation code 24 in the entire program 23 (for example, the line number describing the command statement).

  The importance parameter is information indicating the importance of history information generated by the processing of the history generation code 24. The importance is appropriately set in advance by the programmer according to the content of the code preceding the predetermined command statement.

  For example, when the history generation code 24 inserted immediately after a code that is executed only when an error occurs is processed, for example, the more serious the error is, the higher the degree of importance (for example, “A” in the order of importance) History information in which “any one of“ B ”,“ C ”, and“ D ”) is set is generated.

  On the other hand, when the history generation code 24 inserted immediately after the code executed only when no error has occurred in the program 23, the lowest importance (for example, the importance value is “E”) is obtained. The set history information is generated.

  The block ID is a block ID indicating a block that has been processed in the program 23 including a plurality of blocks, that is, a block ID of a block in which the history generation code 24 is inserted.

  The variable is information indicating the value of a desired variable designated by the history generation code 24 when the history generation code 24 is processed.

  Here, the history generation code 24 included in the program 23 may be described in advance so as to be processed only when the operation mode of the imaging apparatus 10 is in the debug mode, as will be described later. In this way, history information is generated only when the operation mode of the imaging apparatus 10 is the debug mode. On the other hand, when the operation mode of the imaging apparatus 10 is not in the debug mode, the history generation code 24 is not processed, and history information is not generated.

  The processing unit 21 (see FIG. 2) performs processing of the program 23 stored in the storage unit 20. In the present embodiment, the processing unit 21 includes an image processing sub unit 25 and a control sub unit 26. Either or both of the image processing sub unit 25 and the control sub unit 26 perform at least a part of the processing of the program 23.

  The image processing sub unit 25 includes a processor dedicated to image processing, such as a DSP. The image processing sub unit 25 processes a part of the program 23 stored in the storage unit 20, for example, a predetermined block in the program 23, thereby performing a predetermined process on the captured image that has been subjected to the previous image processing by the AFE 18. Post-stage image processing is performed. The subsequent image processing includes, for example, exposure adjustment processing, white balance processing, color interpolation processing, distortion correction processing, viewpoint conversion processing, clipping processing, subject recognition processing, and a predetermined image (for example, a traveling direction when the vehicle 11 travels backward) This includes, but is not limited to, processing for superimposing a guide line) on a captured image.

  Here, when the history generation code 24 included in the program 23 stored in the storage unit 20 is processed, the image processing sub-unit 25 generates history information. Then, the image processing sub unit 25 causes the control sub unit 26 to acquire the generated history information. Here, the image processing sub unit 25 processes the history generation code 24 only when the operation mode of the imaging apparatus 10 is the debug mode.

  The control sub-unit 26 is, for example, a dedicated microprocessor or a general-purpose CPU that executes a specific process by reading a specific program. The control sub unit 26 controls the operation of the entire imaging apparatus 10 by processing a part of the program 23 stored in the storage unit 20, for example, a predetermined block in the program 23.

  For example, the control sub-unit 26 controls the operation of the image sensor 17 to generate a captured image periodically, for example, at 30 fps. In addition, for example, the control sub unit 26 controls the operation of the communication unit 19 to output the captured image subjected to the subsequent image processing by the image processing sub unit 25 to the display device 12 via the dedicated line 22.

  In addition, the control sub unit 26 acquires information (first information) specifying the operation mode of the imaging device 10 from the information processing device 14 via the in-vehicle network 15 and the communication unit 19. Then, the control sub unit 26 determines the operation mode of the imaging device 10 according to the instruction. For example, when the control sub unit 26 acquires the first information designating the debug mode as the operation mode of the imaging device 10, the control sub unit 26 switches the operation mode of the imaging device 10 from the normal operation mode to the debug mode.

  Further, when the control sub unit 26 acquires the history processing setting from the information processing apparatus 14 via the in-vehicle network 15 and the communication unit 19, the control sub unit 26 stores the history processing setting in the storage unit 20. Here, the history processing setting includes, for example, an output condition, a storage condition, and a block priority, as shown in FIG.

  The output condition is a condition for determining whether or not to output history information to the in-vehicle network 15. For example, the output condition includes information (second information) specifying block IDs (“01”, “02”, and “14” in FIG. 4) indicating at least some of the plurality of blocks, and the importance parameter. Information (third information) for designating the value (“A”, “B”, and “C” in FIG. 4). As will be described later, when either (or both) the block ID and the importance parameter included in the generated history information are included in the output condition, the history information is output to the in-vehicle network 15. On the other hand, when both (or any) of the block ID and importance parameter included in the history information are not included in the output condition, the output of the history information to the in-vehicle network 15 is stopped.

  The storage condition is a condition for determining whether or not history information is stored in the storage unit 20. For example, the storage condition includes information specifying block IDs (“01”, “03”, and “15” in FIG. 4) indicating at least some of the plurality of blocks, and an importance parameter (“ C ”,“ D ”, and“ E ”). As will be described later, when one or both of the block ID and the importance parameter included in the generated history information are included in the storage condition, the history information is stored in the storage unit 20. On the other hand, when both or any of the block ID and the importance parameter included in the history information are not included in the storage condition, the history information is discarded without being stored in the storage unit 20.

  The block priority is information that determines the priority of the block ID included in the output condition. For example, in FIG. 4, block IDs “02”, “14”, and “01” are defined in descending order of priority.

  Further, when the history generation code 24 included in the program 23 stored in the storage unit 20 is processed, the control sub unit 26 generates history information. Here, as will be described later, the control sub unit 26 processes the history generation code 24 only when the operation mode of the imaging apparatus 10 is in the debug mode.

  In addition, when the history information is generated and when the history information is acquired from the image processing sub-unit 25, the control sub-unit 26 sends the history information to the in-vehicle network 15 based on the history processing setting stored in the storage unit 20. Decide whether to output.

  For example, when either or both of the block ID of the history information and the importance parameter are included in the output condition of the history processing setting, that is, when the history information satisfies the output condition, the control sub-unit 26 19 causes the history information to be output to the in-vehicle network 15. On the other hand, when both or either of the block ID and the importance parameter are not included in the output condition of the history processing setting, the control sub unit 26 stops outputting the history information.

  Preferably, the control sub unit 26 determines whether or not the data transfer rate from the communication unit 19 to the in-vehicle network 15 is less than a predetermined threshold when outputting the history information. When the data transfer rate is less than the predetermined value, the control sub unit 26 causes the communication unit 19 to output the history information to the in-vehicle network 15.

  On the other hand, when the data transfer rate is equal to or higher than the threshold value, for example, when a lot of history information is generated in a short time and there are a plurality of unoutput history information, the control sub-unit 26 sets the data transfer rate to a predetermined target value. Of the plurality of unoutput history information, the history information having a high block priority based on the history processing setting and the history information having a high importance are given priority to the communication unit 19 in the range of the plurality of unoutput history information. The output history information is sequentially output to the in-vehicle network 15.

  Further, after determining whether or not history information can be output, the control sub-unit 26 determines whether or not to store the history information in the storage unit 20 based on the history processing setting stored in the storage unit 20.

  For example, when either or both of the block ID and importance parameter of the history information are included in the storage condition of the history processing setting, that is, when the history information satisfies the storage condition, the history information is stored in the storage unit 20. Remember. On the other hand, when either or both of the block ID and the importance parameter of the history information are not included in the history processing setting storage condition, the history information is discarded.

  In addition, when the control sub unit 26 acquires an acquisition request for history information stored in the storage unit 20 from the information processing device 14 via the in-vehicle network 15 and the communication unit 19, the control sub unit 26 communicates the history information stored in the storage unit 20. The unit 19 outputs to the in-vehicle network 15. Here, the control sub unit 26 may delete the output history information from the storage unit 20.

  The information processing apparatus 14 includes a connection unit 27, an operation unit 28, a storage unit 29, a display unit 30, and a control unit 31.

  The connection unit 27 is an interface that inputs and outputs information via the in-vehicle network 15. The connection unit 27 is connected to the in-vehicle network 15 when, for example, performing an operation check work and a debug work of the imaging device 10.

  The operation unit 28 includes, for example, a keyboard and a mouse, and accepts user input to the information processing apparatus 14.

  The storage unit 29 is, for example, a memory, and stores various information and programs necessary for the operation of the information processing apparatus 14.

  The display unit 30 is, for example, a liquid crystal display or an organic EL display. The display unit 30 displays various screens based on the display information generated by the control unit 31.

  The control unit 31 is, for example, a dedicated microprocessor or a general-purpose CPU that executes a specific process by reading a specific program. The control unit 31 controls the overall operation of the information processing apparatus 14.

  For example, the control unit 31 outputs the first information specifying the operation mode of the imaging device 10 to the imaging device 10 via the connection unit 27 and the in-vehicle network 15. Specifically, the control unit 31 outputs, to the imaging device 10, first information that designates a debug mode as an operation mode of the imaging device 10 in response to a user input received by the operation unit 28.

  Further, the control unit 31 outputs the history processing setting to the imaging device 10 via the connection unit 27 and the in-vehicle network 15. The history processing setting is determined based on, for example, a user input received by the operation unit 28.

  In addition, the control unit 31 outputs an acquisition request for history information stored in the storage unit 20 of the imaging device 10 to the imaging device 10 via the connection unit 27 and the in-vehicle network 15. The output of the acquisition request is performed according to the user input received by the operation unit 28, for example.

  In addition, the control unit 31 causes the connection unit 27 to acquire history information output from the imaging device 10 to the in-vehicle network 15. Subsequently, the control unit 31 generates display information for displaying a predetermined screen (hereinafter also referred to as an analysis screen) based on the acquired history information. And the control part 31 displays an analysis screen on the display part 30 based on the produced | generated display information.

  Here, the analysis screen will be described. The analysis screen is a screen for the user to visually recognize the operation history of the imaging device 10, and performs various displays based on the history information.

  For example, as shown in FIG. 5, the analysis screen displays a list of block IDs and importance parameters included in the history information, and logs in the order in which the history information was generated (“Time” in FIG. 5). It is a screen. The log is, for example, a variable value included in the history information.

  Further, for example, as shown in FIG. 6, the analysis screen may be a screen that displays a graph with the time when the history information is generated as the horizontal axis and the block ID included in the history information as the vertical axis. A user who sees such an analysis screen can visually recognize which block processing has been executed in accordance with a change in time.

  Next, an example of operations of the imaging device 10 and the information processing device 14 according to the present embodiment will be described with reference to a flowchart shown in FIG. This operation is executed in a state where the connection unit 27 of the information processing apparatus 14 is connected to the in-vehicle network 15.

Step S <b> 100: First, the control unit 31 of the information processing apparatus 14 outputs the first information designating the debug mode as the operation mode of the imaging apparatus 10 to the imaging apparatus 10 via the connection unit 27 and the in-vehicle network 15.

Step S101: Next, when the control sub-unit 26 of the imaging device 10 acquires the first information in Step S100, the operation mode of the imaging device 10 is switched from the normal operation mode to the debug mode.

Step S102: Next, the control unit 31 of the information processing device 14 outputs the history processing setting to the imaging device 10 via the connection unit 27 and the in-vehicle network 15.

Step S103: Next, when the control sub unit 26 of the imaging apparatus 10 acquires the history processing setting of Step S102, the control unit 26 stores the history processing setting in the storage unit 20.

Step S104: Subsequently, the processing unit 21 of the imaging apparatus 10 starts processing of the program 23.

Step S105: Subsequently, when the processing unit 21 of the imaging apparatus 10 processes the history generation code 24 included in the program 23, the history information is generated.

Step S106: Subsequently, the control sub unit 26 of the imaging device 10 determines whether or not the history information in Step S105 satisfies the output condition. When the history information satisfies the output condition (step S106—Yes), the process proceeds to step S107. On the other hand, when the history information does not satisfy the output condition (No at Step S106), the process proceeds to Step S111.

Step S107: When the history information satisfies the output condition in Step S106 (Step S106-Yes), the control sub-unit 26 of the imaging device 10 has a data transfer rate from the communication unit 19 to the in-vehicle network 15 that is less than a predetermined threshold. It is determined whether or not. When the data transfer rate is less than the threshold (step S107—Yes), the process proceeds to step S108. On the other hand, when the data transfer rate is equal to or higher than the threshold (No in step S107), the process proceeds to step S109.

Step S108: When the data transfer rate is less than the threshold value in Step S107 (Step S107-Yes), the control sub-unit 26 of the imaging device 10 causes the communication unit 19 to output the history information of Step S105 to the in-vehicle network 15, and Step Proceed to S111.

Step S109: When the data transfer rate is equal to or higher than the threshold value in Step S107 (No in Step S107), the control sub unit 26 of the imaging device 10 causes the communication unit 19 to store history information with high block priority and high importance. The history information is preferentially output to the in-vehicle network 15, and the process proceeds to step S111.

Step S110: When the control unit 31 of the information processing apparatus 14 acquires the history information output in step S108 or step S109 via the in-vehicle network 15 and the connection unit 27, an analysis screen based on the history information is displayed. Display on the unit 30.

Step S111: When the history information does not satisfy the output condition in Step S106 (Step S106-Yes), after Step S108 or after Step S109, the control sub section 26 of the imaging device 10 stores the history information of Step S105. Determine whether the condition is met. When the history information satisfies the storage condition (step S111-Yes), the process proceeds to step S112. On the other hand, when the history information does not satisfy the storage condition (No at Step S111), the process proceeds to Step S113.

Step S112: When the history information satisfies the storage condition in Step S111 (Step S111-Yes), the control sub unit 26 of the imaging device 10 stores the history information of Step S105 in the storage unit 20, and proceeds to Step S114.

Step S113: When the history information does not satisfy the storage condition in Step S111 (Step S111-No), the control sub-unit 26 of the imaging device 10 discards the history information of Step S105, and proceeds to Step S114.

Step S114: After step S112 or after step S113, the control sub-unit 26 of the imaging apparatus 10 determines whether or not the processing end condition of the program 23 is satisfied. The end condition is a condition that is arbitrarily determined, for example, when an instruction to end the process is acquired from the information processing apparatus 14 or when a predetermined block of the program 23 is ended. When the end condition is satisfied (step S114—Yes), the imaging device 10 ends the process. On the other hand, when the termination condition is not satisfied (No at Step S114), the process returns to Step S105.

  Thus, since the imaging device 10 according to the present embodiment outputs the history information of the processing to the in-vehicle network 15 during the execution of the processing of the program 23, the history information of the processing executed by the imaging device 10 is output. Real-time performance is improved. Further, since the data is output to the vehicle-mounted network 15 such as CAN, the operation analysis of the imaging device 10 can be executed in a state where the imaging device 10 is installed without providing a dedicated port for analysis in the imaging device 10.

  In general, in the in-vehicle network 15 such as CAN, various devices installed in the vehicle 11 communicate using the in-vehicle network 15 such as CAN. Therefore, it is desirable that the amount of information output from the imaging device 10 to the in-vehicle network 15 is small so as not to hinder communication of various devices. The imaging device 10 according to the present embodiment outputs history information only when the operation mode is the debug mode, according to the operation mode specified by the first information specifying the operation mode of the own device. For this reason, compared with the structure which always outputs log | history information, the information content output to the vehicle-mounted network 15 is suppressed.

  In addition, the imaging device 10 outputs history information including the block ID specified by the second information, and stops outputting history information that does not include the block ID. For this reason, the amount of information output to the vehicle-mounted network 15 is suppressed.

  The imaging apparatus 10 outputs history information including the importance parameter of the value specified by the third information, and stops outputting history information not including the importance parameter of the value. For this reason, the amount of information output to the vehicle-mounted network 15 is suppressed.

  Although the present invention has been described based on the drawings and embodiments, it should be noted that those skilled in the art can easily make various changes and modifications based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention. For example, the functions included in each means, each step, etc. can be rearranged so as not to be logically contradictory, and a plurality of means, steps, etc. can be combined into one or divided. .

  For example, in the above-described embodiment, the control sub unit 26 of the imaging device 10 determines whether to store the generated history information in the storage unit 20 based on the storage condition included in the history processing setting. You may determine based on these conditions. For example, the control sub unit 26 may cause the storage unit 20 to store history information in which output to the in-vehicle network 15 is stopped based on the output condition included in the history processing setting. In this way, since only the history information whose output has been stopped is stored in the storage unit 20, the amount of information stored in the storage unit 20 is reduced.
