A domestically produced high precision optical dual station spatial positioning measurement system based on close range photogrammetry technology is carried out.The paper mainly proposes a design scheme for the system,including the overall structure,camera,light source,two dimensional turntable,moving target,processing software,and other aspects of the system design.At the same time,experimental testing is performed on the basis of design and development.Through accuracy analysis with the current high precision measurement instrument excitation tracker,the experimental data shows that its maximum deviation is 0.2mm,meeting the installation tolerance requirement of the main circuit equipment≤0.3mm,verifying that the system can effectively meet the needs of high precision measurement equipment in China,and has a certain degree of feasibility in the localisation of substitution.
