| 摘 要： | 精密工程测量领域,对仪器有着极高的要求,需要定期对仪器的各项性能指标进行检定。仪器的检定和精度标定都需要有一定的基准,并用来评价仪器的性能。文中以球体为基准建立空间标定场,提出利用TLS(整体最小二乘平差)算法拟合球面的方法,并对比分析该方法的可行性;提出在满足精度要求下,参考球的选择方法;理论加实例分析,验证该方法的合理性。

| Abstract: | The field of survey requires high accuracy instrument,which needs checking out all performance indices of instruments periodically.Verification and precision calibration both need a certain benchmark to evaluate the performance of instruments in a rigorous data-processing way.Therefore,this paper based on calibration fieled established by reference balls raises a procedure using TLS to fit the ball,and analyzes its feasibility.Under the demand of precision,it proposes a method of choosing the reference balls.Several analyses about theories and examples are made to verify its feasibility. |
