Study on the Key Technologies of Optical Coordinate Measuring System and Software Design
The Optical Coordinate Measuring System studied in this paper is based upon the digital Close Range Photogrammetry (CRP) technology. This measuring system is suitable for on-field large-scale measurement because of its wide measuring volume, high precision and great efficiency. From the requirement of on-field large-scale measurement, we analyze the principle of binocular vision and the model of general coordinate measuring. We also analyze the software of the system base on the measuring requirement and the working flow of the system. As more and more widely the CAD is used in the industry, the author designs the coordinate measuring software base on the CAD model. The measuring precision of the system is near to ±0.1mm/m. For the moment, the system has been built up, and can measure the typical figures. The precision of the system and the degree of the automatization are satisfied.
