Abstract:
1. An image processing system comprising an imaging means mounted on a subject vehicle, and an image analysis means that acquires images photographed by the imaging means and analyzes the images, wherein the image analysis means acquires plural images with different exposures that the imaging means photographed, detects light spots emitted from other vehicles from the plural images with different exposures, and detects positions of the other vehicles; wherein the plural images with different exposures are an image photographed with a first exposure, and an image photographed with a second exposure greater than the first exposure; wherein the image analysis means extracts a first area containing a first color component from the image photographed with the first exposure to determine the first area to be a first three-dimensional object, and extracts a second area containing a second color component from the image photographed with the second exposure to determine the second area to be a second three-dimensional object; wherein, when there are more than two light spots in a horizontal direction of the image photographed by the imaging means, a position of the other vehicle is calculated from a spacing of a two light spots, wherein the position of the other vehicle calculated from the spacing of the two light spots is compared with a position of other vehicle calculated from a depression angle information of one light spot; and the position of the other vehicle being in a shorter distance from the subject vehicle is control information for controlling the subject vehicle.
