车牌识别云台摄像机通过光抑制屏蔽，电子快门调节，宽动态功能等来实现抓拍车牌：

License plate recognition pan tilt camera is achieved by photoinhibition shielding, electronic shutter adjustment, wide dynamic function and so on.

强光屏蔽：在低照度彩色摄像机的基础上，通过软件的功能，把图像中最亮的部分遮挡。在交通监控中，一般可将大灯的强光遮挡，从而将车牌较清晰的抓拍下来。但是这款摄像机最大的缺点就是软件分辨不清，对于图像最亮部分界定不清，有可能将车牌号码也遮挡，同时无法处理高速运动物体的抓拍。目前国产摄像机在强光屏蔽方面做的比较多，效果各方反映不一。

Strong light shielding: Based on the low illumination color camera, the most bright part of the image is obscured by the function of the software. In traffic monitoring, we usually block the bright lights of the headlights, so that we can capture the license plates more clearly. But the biggest drawback of this camera is that the software is not clear, the brightest part of the image is not clearly defined, it is possible to block the number of the license plate, and can not handle the fast moving object. At present, the domestic cameras do more in the field of strong light shielding, and the effect is different.

可调电子快门：对于高速运动的物体抓拍(高速公路上的汽车车速一般都在70KM/小时以上)，可以通过降低电子快门速度来实现清晰抓拍，一般都是通过手动方式调整。但是这种方式最大的问题就是白天、晚上的照度不一样，必需设置2个快门速度来分别适应白天和晚上的监控。

Adjustable electronic shutter: for high-speed moving objects (the speed of cars on the freeway is generally more than 70KM/ hours), it can be made clear by reducing the speed of the electronic shutter, usually by manual adjustment. But the biggest problem of this way is that the illumination of day and night is different. 2 shutter speeds must be set up to suit the monitoring of day and night.

宽动态功能：这是解决车灯对于抓拍影响的最好的办法，宽动态最早是松下公司提出来的。当背景光过亮时，普通摄像机无法很好家庄电动伸缩门 保定桌椅  保定水处理设备 河北机械加工  保定养老院  保定防水的解决明暗图像的显示问题。

Wide dynamic function: This is the best way to solve the impact of car lights on snapshots. The most dynamic way is the Panasonic Corp. When the background light is too bright, the ordinary camera can not solve the problem of shading and image display very well.

作为智能交通领域确定车辆身份的最重要手段，车牌识别技术为实现交通的智能管理发挥了很大作用，在各项工作中都有车牌识别技术的渗透。

As the most important means to determine the vehicle identity in the field of intelligent transportation, the license plate recognition technology plays a great role in realizing the intelligent management of traffic, and there is a penetration of license plate recognition technology in all the work.
