Patent number: 11042759Abstract: A roadside object recognition apparatus recognizes a roadside object that is present on a travel route on which an own vehicle travels. The roadside object is used for driving control of the vehicle. In the roadside object recognition apparatus, a reflection point acquiring unit acquires, using a radar that emits electromagnetic waves, a reflection-point group of reflection points of the electromagnetic waves reflected by an object that is present on the travel route. An image acquiring unit acquires an image of the travel route using a camera. A reflection point correcting unit corrects the reflection-point group by removing an erroneous reflection point that is determined to be highly likely not to be a reflection point of a roadside object from the reflection-point group through image processing of the image. A shape recognizing unit recognizes a shape of the roadside object using the corrected reflection-point group.Type: GrantFiled: December 11, 2018Date of Patent: June 22, 2021Assignee: DENSO CORPORATIONInventors: Masaya Okada, Shunya Kumano, Takumi Uematsu, Mitsuhiro Tokimasa
