While using Electronic Total Station to measure the deflection of the pressure hull, the measurement error was influenced by different selection of common points. To solve this problem, the coordinate values of pressure hull profiles were established at two different coordinate measuring stations. Selecting different position and number of common points to solve the analog circle initial deflection, we obtained the variation of the initial deflection calculation affected by analyzing the initial deflection and middle error of the measure point. The Simulation results show that the common point should be evenly distributed on the pressure hull, and the number of common points should be controlled at 4-7.
Key words: coordinate transformation / common points / calculation accuracy / pressure hull / radial initial deflectio
