<p>An on-board object detector and on-board object detection method for detecting an object present in a pickup image at a high level of precision. A controller controls a projector to irradiate a line of light while shifting the irradiation angle, and images in the coverage area of the line of light are captured for multiple frames using a camera. Then, shifts in the moving speed of the line of light in the images across the frames are computed based on the images captured, and shifting points in the moving speed of the line of light are detected based on the computed shifts in the moving speed of the line of light in the images across the frames. The position and size of an object that is present in the images are specified based on said detected shifting points in the moving speed of the line of light.</p> |
