差分信号

• Moreover , the identifying and processing software of image is applied for storingextracting object counting the character of object computing errors and so on . at last , the track precision of object can be got . this system not only applies dalsa camera and pc - dig collecting card to ensuring real time of collecting image , but also applies software compiled by vc + + to improving processing speed and flexibility operating convenience
  该系统不仅采用先进的dalsa航空用数字相机和性能优越的pc - dig图像采集卡，以及低电压差分信号( lvds )的接口模式，用很低的电压摆幅来保证在相对较短的距离内( 10 - 15m )实现高速( 400mbps )数据传输，从而保证了图像采集的实时性，同时用vc + +编写的软件使图像处理速度高，灵活性强，操作方便。
