Patent attributes
A three-dimensional object detection device includes an image capturing unit, an image conversion unit, a three-dimensional object detection unit, a three-dimensional object assessment unit and a control unit. The image conversion unit converts images obtained by the image capturing unit to create bird's-eye view images. The three-dimensional object detection unit detects a presence of a three-dimensional object within a detection area based on differential waveform information or edge information. The stationary three-dimensional object assessment unit assesses whether the detected three-dimensional object is a shadow of a tree along a road traveled by the host vehicle. The three-dimensional object assessment unit assesses whether the three-dimensional object detected is a vehicle within the detection area. The control unit suppresses the assessment that the three-dimensional object is a vehicle when the detected three-dimensional object was determined to be a shadow of a tree along the road traveled by the host vehicle.
