As described in Publication No. 79, a pulse generator is connected to the wheels of a traveling trolley equipped with a buried object detection sensor, and the measurement position is recognized by counting the number of pulses emitted by the pulse generator as the wheels rotate. I was taking it.

裂する等の可能性があった。However, in this method, if the road surface conditions on which the wheels are running are bad, phenomena such as the wheels slipping or lifting off the road surface occur, and the number of pulses generated by the pulse generator connected to the wheels may vary. If an error occurs in the running position of the buried object and the reflected waves from the buried object are image processed based on the number of pulses of the pulse generator, the image position of the buried object may deviate from its original position due to the positional shift of the measurement point. There was a possibility that the video itself would be split.
