An automobile distance detection system includes an image camera system which photographs an object which exists in a required range external to an automobile, from a plurality of different directions and obtains a plurality of pictures, and a picture processing unit which processes the plural number of pictures photographed by the camera system and outputs a distance distribution for an entire picture. The image processing unit includes a coincidence calculation element which performs high-speed calculation of a degree of coincidence for each required region, and corresponding to the plural number of pictures photographed by the camera system, and a discrepancy amount determination element determines discrepancy amounts corresponding to the plural number of pictures on the basis of a minimum value for the coincidence, as information relating to the distance distribution.
A distance detection system for an automobile, having an imaging system for imaging external objects in a required range from a plurality of different directions and for obtaining a plurality of pictures corresponding to said different directions, and a picture processing unit for processing said pi
A distance detection system for an automobile, having an imaging system for imaging external objects in a required range from a plurality of different directions and for obtaining a plurality of pictures corresponding to said different directions, and a picture processing unit for processing said pictures and for outputting a distance distribution in an entire image of said required range, the picture processing unit comprising: coincidence calculation means for dividing said pictures of said required range into a plurality of small regions and for performing a calculation of the coincidence between each of said plurality of small regions in one of said pictures and at least one region in at least one of the other pictures; discrepancy amount determination means for determining discrepancy amounts at corresponding small regions over an entire picture on the basis of a maximum value of the degree of coincidence corresponding to said regions.
