Abstract

The invention provides an intelligent traffic digital monitor integrating functions of camera, license plate recognition, snapping, speed measurement and network transmission. The monitor comprises a charge coupling camera, a front end circuit of the charge coupling camera and a field programmable gate array. The charge coupling camera acquires an image signal of an automobile; the front end circuit of the charge coupling camera reads out a BAYER formatted analog signal acquired by the charge coupling camera and converts the analog signal into a digital image signal; and the field programmable gate array converts the BAYER formatted digital image signal into an RGB formatted digital image signal, converts the RGB formatted digital image signal into a YUV formatted digital image signal, and simultaneously completes the vehicle license plate recognition and the compression of the YUV formatted digital image signal, judges whether the automobile violates the traffic rules according to the received ground induction coil trigger signal and traffic light control signal, and transmits license plate recognition, image compression and traffic violation data to the client through a network interface.

Description

technical field [0001] The invention belongs to the field of traffic management, in particular to an intelligent traffic digital monitor and its application. Background technique [0002] With the development of the economy, there are more and more motor vehicles, so it is necessary to effectively manage the motor vehicles and their drivers participating in the traffic, otherwise, traffic accidents will increase, which will inevitably cause huge economic losses and casualties. The occurrence of traffic accidents is often related to illegal driving, among which speeding and not following the instructions of signal lights are particularly common. Therefore, it is necessary to monitor the speed of motor vehicles participating in the traffic and whether they are driving according to the instructions of signal lights, and license plate recognition is a must in monitoring. solved problem. [0003] Regarding license plate recognition and whether to drive according to the signal li...
