利用OPENCV来打开USB摄像头，用到了cvCaptureFromCAM(-1)函数，选择默认的第一个摄像头作为输入，同时，对OPENCV中的视频跟踪进行了实验。-OPENCV to use the USB camera, use the cvCaptureFromCAM (-1) function, select the default first camera as an input, the same time, the video track OPENCV experiments we

实现功能：同时采集两路USB摄像头数据，并显示，具有图片保存功能（点击左键保存图片，并暂停视频；右键继续视频）。-The realization of functions: simultaneous acquisition of two USB camera data, and display, has pictures of preserved function ( click the left button to save the image, and the right key to pa

两个摄像头视频采集；同时采集两路USB摄像头数据，并显示，具有图片保存功能-Two camera video capture simultaneous acquisition of two USB camera data, and display, save the picture function

本程序开发环境：vc和opencv 整体功能：是为了实现车载视频中车牌自动跟踪，检测，，定位，识别，视频中物体的跟踪必须是手动圈住才行，摄像头使用的是usb摄像头. 打开摄像头，可以看到视频中画面，移动鼠标圈住物体，可以自动跟踪。-This program development environment: VC and opencv The overall function: in order to realize the video vehicle license plate auto
