Because the general high-definition camera adopts digital transmission mode, the system is simple and convenient to build, stable and reliable in operation and low in maintenance cost. Therefore, the high-definition camera mode has considerable advantages in comprehensive cost and use effect. With the price of industrial-grade and high-definition cameras gradually decreasing, high-definition camera capture mode will be the mainstream mode for the development of electronic police system for running red lights in the future.
Principle of electronic police camera:
Video trigger mode uses image processing and analysis technology to locate and track the vehicles in the intersection video, and realizes accurate analysis of the vehicle trajectory, thus distinguishing various illegal behaviors such as running red lights, not driving according to lane signs, and changing lanes illegally.
The video trigger mode has the characteristics of powerful and comprehensive function, convenient construction and maintenance (no need to bury and maintain the ground loop) and reasonable cost. With the rapid improvement of the detection performance of this kind of products, the video trigger mode is gradually replacing the ground loop trigger mode and becoming the development direction of modern electronic police system.
