Publication number: 20210256728Abstract: In an object detection apparatus for detecting a position of an object based on at least measured distances to the object as measurement results by a plurality of ranging sensors, a speed difference calculator calculates, for each of candidate points representing the position of the object, a relative speed difference between the relative speeds of the candidate point acquired from the plurality of ranging sensors. The candidate-point determiner determines that a candidate point of the candidate points, the relative speed difference of which is equal to or greater than a predetermined value, is a virtual image of the object. An object detector detects the position of the object based on positions of the candidate points each determined to be a real image after removal of the candidate points each determined to be a virtual image from all of the candidate points.Type: ApplicationFiled: May 6, 2021Publication date: August 19, 2021Inventors: Masakazu IKEDA, Mitsutoshi MORINAGA
