Description

The present invention relates to surveying devices, surveying methods and programs for surveying public facilities, water and sewage systems (eg, manholes, pipelines), propane gas locations, and locations of outdoor buildings such as highway lights and utility poles.

Conventionally, there has been a need to measure the exact latitude and longitude of an outdoor building in order to grasp the exact location.

For example, it is important for a trader who lays cables and the like using utility poles to accurately grasp the location of utility poles. Therefore, using a map application installed on a smartphone equipped with GPS (Global Positioning System), the location of a utility pole, which is an object, is measured. In this method, a user carrying a smartphone moves to the position of an object and records the location by GPS (see Non-Patent Document 1).

In addition, RTK (Real Time Kinematic) -GPS surveying is also known. This is to accurately measure the position of a survey point away from the reference point by a plurality of satellites by correcting from the reference point based on the latitude, longitude, and altitude of the known reference point.

The movement route acquisition module 143 acquires its own movement route (step S23). In step S23, the movement route acquisition module 143 uses a movement path starting from one survey point measured by the process of step S20 described above and ending at the other survey point measured by the process of step S25 described later. get. The movement route acquisition module 143 acquires the movement route from the start point to the end point by the sensors owned by the module 143.

The recording module 130 records the acquired movement route (step S24). In step S24, the recording module 130 records the one surveying point as the starting point, the other surveying point as the ending point, and the movement path between them in association with each other.

The survey module 140 surveys the latitude, longitude, and altitude of the survey point as survey data by RTK-GPS survey (step S25). The process of step S25 is the same as the process of step S20 described above. As a result, the other survey point will be surveyed.

The input reception module 141 accepts the input of the detailed data of the survey point (step S26). The process of step S26 is the same as the process of step S21 described above.

The recording module 130 records the survey result of the survey point and the detailed data of the survey point (step S27). The process of step SS27 is the same as the process of step S22 described above.

As a result of these processes, as the surveyor moves from one survey point to the other survey point, the surveying during this period is continuously performed.

The surveying end determination module 144 determines whether or not the surveying of all the surveying points has been completed (step S28). In step S28, the survey end determination module 144 satisfies the number of preset survey points, whether or not the last preset survey point is surveyed, and the predetermined distance from the last surveyed survey point. This judgment is executed based on whether or not the above movement has been performed.

If the surveying end determination module 144 determines in step S28 that the surveying of all the surveying points has not been completed (step S28 NO), the surveying apparatus 100 re-executes the process of step S23 described above.

On the other hand, in step S28, when the survey end determination module 144 determines that the surveying of all the survey points has been completed (step S28 YES), the movement route acquisition module 143 acquires the movement route after the last survey point. Cancel (step S29). In step S29, when the movement route acquisition module 143 has acquired the movement route starting from the last survey point, the movement route acquisition is canceled and the movement route is deleted. Further, when the movement route acquisition module 143 has not acquired the movement route starting from the last survey point, the movement route acquisition module 143 executes the next process as it is.

The display module 145 displays a map near the survey point based on the latitude, longitude, and altitude of the survey point (step S30). In step S30, the display module 145 displays a map near the survey point recorded by the process of step S22 and the process of step S27 described above by the map application installed in the display module 145. In addition, this map may be created by CAD or GIS data.

The display module 145 displays the survey points surveyed this time on this map (step S31). In step S31, the display module 145 superimposes a marker, an icon, or the like indicating the survey point on the position on the map corresponding to the latitude, longitude, and altitude of the survey point recorded by the process of step S22 and the process of step S27 described above. Let me display it.

The survey point 410 indicates the position of the surveyed place on the map, and the survey line 420 connects the survey points 410 to each other. When the survey point 410 is a cable laying object, the survey line 420 indicates a cable to be laid between the cable laying objects. Line 430 represents the result of GPS survey by a terminal such as a smartphone. As shown in FIG. 8, only the GPS survey by the terminal has a wider error with respect to the actual point than the survey result by the RTK-GPS survey. Therefore, RTK-GPS surveying is effective in order to suppress an error with respect to an actual point.

The display module 145 may display the survey result of the survey point 410 and the detailed data of the survey point 410 by receiving the input to each survey point 410 by the input reception module 141.
