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,做了剔除粗差点的研究,并给出了三点坐标法测圆心、多点坐标法测圆心以及剔除粗差点的VB程序,易于计算.结果表明,点的构形对测量圆心的精度影响较大,选择合适的构形,可以提高测量精度.通过对坐标法和对模拟试验数据的计算与分析得知,点在圆周上分布越均匀,圆心位置的精度最高,点的构形呈正多边形分布时,中心位置的精度最高;点分布的圆弧越小,拟合圆心的精度就越差,且不能满足中心位置的精度要求.采用测量圆周上多个点坐标的方法,对圆心坐标进行平差计算及精度评定时,相比于3点坐标法,可以提高拟合圆心的精度及可靠性,其构形对精度的影响没有3点坐标法大.研究结论具有实用性和有效性.在苏通大桥钢护筒中心位置检测中得到了较好的应用.

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
