Study on the Techniques of Optical Coordinate Measuring System

ZHU Ji-gui,WANG Xin,WANG Da-wei,YE Sheng-hua(State Key Lab of Precision Measuring Technology and Instruments,Tianjin University,Tianjin 300072,China)  
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 disturbance.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.
