Coordinate measuring system which based on the theory of binocular stereo vision is widely used in many areas, whereas their effective measuring ranges are usually not larger than ten meters. In modern times the surveillance of large scale is used more and more in the civil and military area with the development of camera and computer technology. So based on this requirement this paper developed a new measuring model for this binocular stereo vision measuring system which is proper used in outdoor surveillance to get the 3D coordinate of the moving object. When the distance between two cameras is hundreds meters, the installation and camera calibration are quiet simple and convenient without expensive calibration apparatus and an elaborate setup or a planar pattern shown at a few different orientations or complicated camera imaging model and the parameters of math model are easy to get. After building the model of measuring system error analysis is performed to show influence of every parameter on the measuring system error. Both computer simulation and real data have been used to test the validity of our new simple measuring system model.
