traffic surveillance process and device
First Claim
1. A method of surveying a traffic scene comprising the steps of:
- measuring a speed of a vehicle within the traffic scene with a speed sensor and converting the measured speed into modulated signals;
optically recording the traffic scene in a recording medium of an electro-optical camera;
storing said modulated signals on a soundtrack of the recording medium in synchronism with the optically recorded traffic scene; and
displaying the optically recorded traffic scene on a reproduction device in synchronism with a display of the measured speed.

Abstract
A traffic surveillance system measures a speed of a vehicle within a traffic scene, optically records the traffic scene, and reproduces the traffic scene on a display in synchronism with a display of the measured speed. The system includes a speed sensor which measures the speed of the vehicle within the traffic scene and an electro-optical camera having a recording medium in which video signals representing the traffic scene are stored. The camera is equipped with an audio input and output connected to a soundtrack of the recording medium. The audio input receives modulated signals of the measured speed for storage in the soundtrack in synchronism with the video signals. The measured speed signals and the video signals are combined in a video mixer and reproduced on the display.

4. An apparatus for surveying a traffic scene comprising:
-
a speed sensor to measure a speed of a vehicle within the traffic scene; a modulator to generate modulated signals which represent the measured speed; an electro-optical camera having a recording medium in which video signals representing the traffic scene are stored and an audio input and output connected to a soundtrack of the recording medium, said audio input receiving said modulated signals for storage on the soundtrack; a demodulator to convert the modulated signals which are received from the audio output of said electro-optical camera into demodulated signals; and a display to display the measured speed in accordance with the demodulated signals. - View Dependent Claims (5, 6, 7, 8, 9, 10)
