道路车辆监控系统中灯光补偿技术研究

Research of Light Supply Technology for Vehicles Surveillance

全天候车辆监控系统中,对于夜间高速行驶车辆抓拍是一个技术难题,本文阐述了一种基于视频同步技术的图像抓拍灯光补偿系统的解决方案。系统设计中周密计算了补偿灯光的光通量和闪光时间,采用了新的同步技术,即以视频场同步信号为基准定位,保证了来车触发信号、摄像机抓拍信号和闪光灯照明信号三者完全同步。实测数据表明,该系统的性能达到了实用化要求。

Among all-weather vehicles surveillance systems, it is a technological targets in the dark. This paper technology. techniques, introduced an image capture and light After calculating the supply light＇s light lux and flashlight that is, by localizing the vertical sync signal, the system problem to snatch at the high speed supply system based on video sync ＇s time, we have applied new sync keeps the synchronization of vehicleactuated signals, snatching signals and flashlight signals. The result of experiments shows the system has reached the client requests.
