Abstract
The purpose of the present invention is to provide an object detection device which is capable of accurately estimating the height of a road surface and is capable of reliably detecting an object present on the road surface. This object detection devicedetects objects upon a road surface, and is equipped with: a stereo camerafor capturing images of the road surfaceand the road shoulderand generating image data; a three-dimensional data generation unitfor calculating disparity data for the pixels in the image data; a shoulder structure detection unitfor using the disparity data and/or the image data to detect shoulder structures; a structure ground-contact position derivation unitfor deriving the ground-contact position of a shoulder structure; a road surface position estimation unitfor estimating the height of the road surfacefrom the ground-contact position of the shoulder structure; and an object detection unitfor detecting an objectupon the road surfaceby using the disparity data and the road surface height to separate disparity data corresponding to the road surfaceand disparity data for the object.
