One, application background
With the motor vehicle large-scale popularization application, all kinds of motor vehicle and the illegal events began to breed and spread and use of motor vehicle traffic tools as a proportion of cases increase gradually. Collection, statistics, and analysis of all kinds of cases, found that most of the cases of transportation are motor vehicle. Construction road vehicle information automatic monitoring system (bayonet), motor vehicle trajectory for continuous automatic detection and records, through the analysis of data and combining the case found clues, is an important means of cracked the case, and then improve the city public security environment, improve the public travel safety coefficient.
Previous monitoring system is mostly at the same time record after vehicle car head a close-up images and the vehicle's panoramic image two photographs, resolution maximum is 768 * 576, although for the vehicle management will be enough to use, but for deck vehicles, vehicle, road vehicles and list for slightly is insufficient, because of the need to more clearly see driving personnel's facial features and as much as possible the details of the vehicle and so on. Therefore, using 2 million pixels record vehicle image highway vehicle intelligent monitoring system, vehicle image resolution 1600 * 1200 pixels, only a collection ZhangQuanJing photos, not only can clearly see the company take the personnel's facial features, also can high quality capture license plates, has the very high automatic license plate recognition, the recognition rate is above 98%.
Two, the function overview
System has vehicle capture, image recording, illegal evidence, license plate recognition, those have been supervised alarm, flow statistics, data transmission, equipment management, and other functions, support are coil and pure video trigger two ways.
Three, the technical implementation
System integration the video dynamic detection, pattern recognition, digital signal acquisition, communication network and database management and so on many technology, the use of public security image private network, boundary access platform, public security network for data transmission.
(1) when the vehicle trigger B coil, the system to record the current moment TB; (2) when the vehicle trigger coil A, the system to record the current moment TA, and at the same time, the vehicle's speed calculation, including DB for B coil and the distance between A coil; (3) vehicle detector is trigger signal to trigger the hd network camera image capture, (4) at the same time, hd network camera given trigger signal synchronous flash fill light. (5) hd network camera capture the vehicle image and produce images stored in the host; 6 system will vehicle image processing and identify the vehicle information through the network to upload to control center server.
Four, the application and the customer benefit
Hd security bayonet provides abundant practical application functions, improve the way dynamic control and security, line mapping, traffic management level, in combating and preventing crime and treatment of sudden events, regulate the urban traffic order and other applications have played an important role.
Five, involving the product
(a) JSC hd paparazzi cameras.
(2) JSC highway vehicle intelligent monitoring system software.
(3) JL bayonet electronic police system software.
