Abstract

PURPOSE: To enable detection of position of vehicle, by installing two cameras with different distance and height from the reference point and displaying with distance the apparent front and rear position obtained from an image signal.
CONSTITUTION: The reference point is defined as P0, heights of cameras: f, e from the point P0, h2, h1. The apparent rear position of a vehicle B to be measured from the camera e is defined as K2 and the rear position as K4. As ΔeK5K1 and Δy1P1K1 and ΔfK6K3 and Δy1P1K3 are similar, the distance l1 between vehicle front position P1 and reference point P0 is obtained. Similarly the rear position distance l2, etc. are obtained. Thus, from the vehicle existing position obtained by a single camera, an accurate position of the vehicle can become avilable. By sequential or simultaneous processing, vehicle existing position, vehicle height, between-vehicle distance, vehicle length, etc. can be detected consecutively or simultaneously.
