英语翻译对三点坐标法及多点坐标法法测量圆心坐标最佳构形进行了详细的理论证明,进行了多方面的精度计算与分析,做了剔除粗差点

Coordinates of the three coordinate method and multi-point measurement of the center coordinates of the best configuration for a detailed theoretical proof for the calculation and analysis of a wide range of precision, made almost of removing rough, and gives the three coordinates Measuring center, multi-center coordinate method, and removing the coarse measuring almost the VB program, easy to calculate。 The results show that the point configuration on the accuracy of measuring the center of a larger, select the appropriate configuration, can improve the measurement accuracy。 Through the coordinate method and the calculation of the simulation and analysis of test data that the point distribution more uniform in circumference, the center position of the highest accuracy, was a regular polygon configuration point of distribution, the center position of the highest accuracy; point distribution of the arc The smaller, the worse the accuracy of fitting the center and the center can not meet the accuracy requirements。 By measuring coordinates of multiple points on the circumference method, the center coordinates of the adjustment calculation and precision of assessment when compared to the 3-point coordinate, the center can improve the accuracy and reliability of the fitting, the configuration is not on the accuracy 3:00 Coordinate large。 Conclusion of the study is practical and effective。 Su Tong Bridge in the center of steel casing to get a good test application
