ROAD SURFACE STATE DETECTION DEVICE, ROAD SURFACE STATE DETECTION METHOD, AND ROAD SURFACE STATE DETECTION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a road surface state detection device for correctly detecting slope of a road surface, a road surface state detecting method, and a road surface state detection program.;SOLUTION: An image acquiring part acquires an image, from the acquired image, a divisional line recognition part extracts a divisional line which divides a left side of a lane displayed on a road surface and a divisional line which divides a right side of the lane. A road surface state determining part determines slope information showing change of the slope of the road surface, based on a direction of the divisional line which divides the left side and a direction of the divisional line which divides the right side.;COPYRIGHT: (C)2013,JPO&INPIT
