In a previous paper the theoretical possibility of using CCD images as a distance sensor in the case of the car following systems was investigated. It was assumed that we are disposing of a pattern recognition software able to spot the image of the previous car. The proposed solution consisted in two operations: the estimation of the distance between the cars by the aria of the CCD image (in pixels) and the validation of the estimated distance by stereoscopy. The present paper is continuing the approach, by experimental tests, that are proving its efficiency. The pattern recognition software is aimed to the license plate of the followed car. Some no. of pixels/distance mappings were measured for different focal lengths and the corresponding characteristics were analyzed.
