Title: Object detection device, object detection system, moving object and object detection method
Inventor: KONO KENJI
IPC: G06T7/00
Filed: 2019-09-24
Abstract: To improve performance of an object detection device to detect objects.SOLUTION: An object detection device is configured to execute a road surface detection process, an object parallax determination process, and an object detection process. The road surface detection process estimates a position of a road surface based on a first parallax map. The first parallax map is generated based on output by a stereo camera, and a parallax is associated with a two-dimensional coordinate consisting of a first direction and a second direction. The first direction corresponds to a horizontal direction in an image captured by the stereo camera. The second direction intersects the first direction. The object parallax determination process determines the parallax as an object parallax when the number of appearances of the parallax for each coordinate range in the first direction of the first parallax map exceeds a predetermined threshold value according to the parallax. The object detection process converts information on the object parallax into a point group in an x-z coordinate space, and detects an object by extracting cohesion of point groups.SELECTED DRAWING: Figure 5
