Abstract
The invention provides a control technology achieving plate number video detecting and flash shooting for a vehicle recognition system. LED lamps which are constantly turned on and small in power are placed around a camera. When vehicles pass through passageways or other traffic occasions, clear plate number images can be obtained from image output of the camera. When detecting the passing vehicles in time through the plate number detection technology, the vehicle recognition system can immediately control a flash lamp to flash, flashing is synchronous with exposure of the camera, and therefore the whole shooting process is completed, and the pictures where plate numbers, the outlines and types of the vehicles, the colors of vehicle bodies and the conditions inside cabs can be clearly seen can be obtained. The photographs of the passing vehicles can be shot through supplementary lighting of the flash lamp without external triggering equipment.
Description
Technical field
The technology of the present invention relates in intelligent transportation, safety-security area, captures the occasion of identification maneuver vehicle under the environment of night or illumination deficiency.
Background technology
Under the environment of night or illumination deficiency, vehicle identification system requires that shooting can see car plate clearly, also can see the picture of vehicle ' s contour, vehicle, body color, driving indoor situations clearly, needs to use flashlamp to carry out flash of light and takes.All adopt at present the mode installing exterior vehicle checkout equipment additional, namely when external detection equipment detect vehicle by time, send trigger pip to system, system receives rear control flashlamp and sends high light and complete shooting.But in some cases, the restriction by environment and demand can not install outside vehicle equipment additional, cannot use flashlamp, also just not reach the requirement of vehicle identification system.
Summary of the invention
What China's automotive number plate adopted is reflecting type car plate, just car plate can be illuminated around video camera with more weak lamp.That the present invention adopts Chang Liang, that power is lower LED is positioned over around video camera, when vehicle is by gateway or other traffic scene, can obtain license plate image clearly in the image output of video camera.Vehicle identification system adopts car plate detection technique the vehicle passed through can be detected in time, now control flash fire immediately and with the exposure sync of video camera, complete whole shooting process, can obtain and can not only see car plate clearly, the picture of vehicle ' s contour, vehicle, body color, driving indoor situations can also be seen clearly.Under achieving the condition without external trigger equipment, use flash lighting shooting by the demand of vehicle.
