摘要

The system comprises a vehicle with a video camera (2) in the driver's cab for taking pictures of the traffic space from the viewing angle of a driver. To the video camera is connected a video recorder (3). A process computer (1) is controlled by appropriate software and supplied by the camera video signal from the video recorder in an analog manner. The computer controls the functions of the video recorder during playback. The analog video signals from the recorder are continuously digitised. After a specified evaluation, determined by the computer software, the reproduced video image is evaluated by stopping the tape playback of the recorder during the generation of a corresp. control signal by the computer. ADVANTAGE - Improved examination system with ON-line or OFF-line evaluation.
