METHOD OF OPERATING A VEHICLE TAIL LIGHT DETECTION SYSTEM FOR AN AUTOMATED CARWASH AND VEHICLE TAIL LIGHT DETECTION SYSTEM

摘要

In a carwash a vehicle is conveyed via a conveyor. An initial image of a rear portion of the vehicle traversing the carwash is captured. The initial image is processed and a recorded light intensity of a tail light of the vehicle is generated. A benchmark light intensity is derived from the light intensity and a margin of error. Sample images of the tail lights of the vehicle are periodically obtained. The sample images are processed to derive sampled tail light intensities. The sampled tail light intensities are compared to the benchmark tail light intensity. The conveyor is stopped if a sampled tail light intensity is greater than the benchmark tail light intensity.
