road surface research program and the road surface inspection apparatus

摘要

PROBLEM TO BE SOLVED: To detect the deterioration of the road surface at an early stage.;SOLUTION: A road surface inspection device 10 detects an abnormal region on a road surface from the road surface on a road image captured with a camera 31. The road surface inspection device 10 determines whether the detected abnormal region overlaps a trace on the road image, along which the wheels of a patrol car 3 are expected to pass on the road surface. When the abnormal region overlaps the trace of wheels, the road surface inspection device 10 determines whether an acceleration at the measurement time corresponding to the captured time of the road image among the accelerations measured during driving on the road surface with a G-sensor 32 is outside a predetermined range.;COPYRIGHT: (C)2013,JPO&INPIT
