An object detection device is configured to execute a first process, a second process, and an object detection process (third and fourth processes). The first process estimates a shape of a road surface in a real space on the basis of a first disparity map. The first disparity map is generated on the basis of an output of a stereo camera that captures an image including the road surface, and is a map in which a disparity obtained from the output of the stereo camera is associated with two-dimensional coordinates formed by a first direction corresponding to a horizontal direction of the image captured by the stereo camera and a second direction intersecting the first direction. The second process removes from the first disparity map a disparity for which a height from the road surface in the real space corresponds to a predetermined range on the basis of the estimated shape of the road surface to generate a second disparity map. The object detection process (third and fourth processes) detects an object on the basis of the second disparity map.

Object detection device, object detection system, mobile object, and object detection method

An object detection device includes a processor. The processor acquires or generates a first disparity image generated on the basis of an output of a stereo camera mounted in a mobile object. In the first disparity image, pixels representing disparities are arranged on a two-dimensional plane formed by a first direction corresponding to a base-length direction of the stereo camera and a second direction intersecting the first direction. The processor approximates a relationship between a coordinate, in the second direction, of a road surface in a direction of travel of the mobile object and a disparity representing the road surface with two straight lines, the relationship being included in the first disparity image.
