We must always measure a distance from the own vehicle to the front one to prevent the collision accident. In this paper the authors desribed a new technique for measuring the distance using stereoscopic images. A vehicle can be recognized as a set of object points that are same distance from the stereo cameras. So, disparity map is projected in the depth direction. This map is called 'Projection Disparity Map'. In the projection disparity map the disparities of the vehicle are translated into the straight line. So one can detect the front vehicle by extracting the straight line. For verifying this method, the authors applied it to the stereosocpic images that are acquired on the expressway. And the efficieny was shown by experiments.
