If the role of the eye is to see, then the role of the road monitoring camera is to monitor the target objects such as vehicles, drivers, pedestrians, and markers in the moving road. It requires 24 hours a day and 24 hours a day, and requires endurance. On the basis of this, it is also necessary to be able to capture the target object's feature information (such as number plate, color, face, outline, shape, etc.) in real time and clearly. To sum up, in fact, the role of road surveillance cameras are mainly the following three points: "see" "record" "remember."
First, traffic monitoring
The front-end camera transmits the real-time image of the monitored area back to the traffic command center via the transmission line. The traffic commander grasps the traffic conditions of the intersections and road sections in real time, such as the traffic volume of the road section, the status of the signal lights, the violation of the motor vehicle, and the traffic accident. This information can help the traffic management department to take appropriate measures and handle the plan in a timely manner. It can promptly release information by broadcasting and television media and in front of the traffic-induced display screen to inform drivers and pedestrians on the road for effective traffic guidance.
Second, real-time video
Video images transmitted to the traffic command center will be automatically saved to the video server as evidence for the handling of various accidents such as traffic accidents, violations of motor vehicles, and public security crimes.
Third, information acquisition
According to specific monitoring requirements, special information (such as number plate, color, face shape, outline, shape, running status, etc.) of target objects such as vehicles, drivers, pedestrians, and markers that are in motion on the road is collected to provide control. The software or equipment performs analysis and processing, outputs analysis and decision plans and processing plans in accordance with the set algorithm, and can automatically control the entire system to perform linkage processing. On the basis of effectively obtaining real-time and clear image information, many intelligent electronic devices and control systems based on video images have been derived, such as: electronic police, road bayonet, video detection, license plate recognition, face recognition, and automatic deployment. and many more.
