摘要： This device for detecting a road surface state includes: a stereo camera including a plurality of cameras that each image a road surface in front of a vehicle and are arranged such that a parallax is vertically generated; and an arithmetic processing circuit that vertically searches for corresponding points of a plurality of images taken by the plurality of cameras of the stereo camera, to thereby calculate a parallax, and calculates a height of the road surface as a state of the road surface on a basis of the calculated parallax.

摘要： In this road surface displacement detection device, for each frame of an image obtained by a stereo camera that images a road surface in a movement direction of an object such as a vehicle, for example, an arithmetic processing circuit detects heights of the road surface at a plurality of points for detection at different distances from the stereo camera, and superimposes information about the heights at the plurality of points for detection, which are detected for a plurality of frames, on each other while considering a movement distance of the object between the plurality of frames.
