Abstract: Provided is a travel road recognition device that can accurately recognize a travel road end of a travel road on which an own vehicle travels. A travel road recognition device of the present invention is a travel road recognition device that recognizes the travel road end of the travel road on which an own vehicle 301 travels, and includes: a laser radar 101 that emits a laser bean from the own vehicle 301 toward the travel road; a road surface determination unit 203 that obtains a cross slope of the travel road based on coordinate values of a point cloud obtained by the laser radar 101; and a road end determination unit 204 that obtains a change point at which a slope angle changes in the cross slope of the travel road obtained by the road surface determination unit 203, and obtains coordinate values of at least one travel road end of both sides in a cross direction of the travel road based on the coordinate values of the change point.

Abstract: Provided is an object detection device capable of improving efficiency while ensuring detection accuracy.
An object detection device 1 includes a point cloud acquisition unit 201 that acquires point cloud data of an object according to a scanning result of a LiDAR 101, an object detection unit 204 that detects an object based on the point cloud data, and a reliability determination unit 205 that determines a reliability in a detection result of the object detection unit 204. The point cloud acquisition unit 201 controls the scanning range and the irradiation density of the LiDAR 101 on the basis of the reliability.
