摘　　要：光学坐标测量系统是建立在数字近景测量技术基础上的一种新型精密测量系统.它具有便携性好、精度高、测量范围大、受环境干扰小等优点,适合工业工程的现场测量.针对工业现场精密测量的需求,分析了立体视觉原理以及通用坐标测量的数学模型.目前系统的精度接近±0.1mm/m,整个系统已初步成型,能够对实物工件进行测量,其测量精度、自动化程度令人满意.The Optical Coordinate Measuring System is based upon the technique of the digital close range photogrammetry（CRP）. This measuring system is suitable for on-field measurement of industrial engineering because of its good portability, high precision, wide measuring range and low surroundings disturb- ance. From the requirement of on-field measurement, the principle of binocular stereovision and the model of general coordinate measuring system are analyzed. The measuring precision of the current system is close to ±0. 1 mm/m, and the building of the system has been built up on the whole, which can measure the real objects,and its measuring precision and automatization degree are famous.
