At this time, the camera 13 and each sensor 6 are installed so that the imaging range of the camera 13 and the detection range of each sensor 6 overlap. The video imaged by the camera 13 is output to the decoder unit 11 as image data.

  The decoder unit 11 decodes the image data input from the camera 13 and outputs the decoded image data to the display control unit 3.

  The memory unit 12 stores information related to the vehicle width of the vehicle 7. Further, the memory unit 12 stores a correspondence relationship between the video imaged by the camera 13 and the position of the obstacle 8 calculated by the position detection unit 2 using each sensor 6. That is, the image of the camera 13 and the position information calculated using each sensor 6 are stored in association with each other so that the position of the obstacle 8 in the image can be understood.

  The display control unit 3 includes the image data input from the decoder unit 11, the distance display gauge 9 based on the position of the obstacle 8 detected by the position detection unit 2, and the vehicle 7 stored in the memory unit 12.
