| 摘 要： | 分析了光电经纬仪的测量误差来源及其影响,采用了星体角度法分离得出各项系统误差,并在此基础上编程实现了对测量结果的实时修正。使用这种方法修正了某型号光电经纬仪的测量数据,并对修正前后的测量精度进行比较,得出的结果表明,该修正方法可以使光电经纬仪的精度从原来的15″左右提高到5″以内,也就是修正效果明显,达到了提高光电经纬仪测量精度的目的。

| Abstract: | After analyzing the source and effect of measuring error, all the system errors of a photoelectric theodolite were obtained with means of shooting star,based on which, programs to fulfill the real-time error-correction for the photoelectrical theodolite's measuring result were given. The measuring data from a certain kind of photoelectrical theodolite were corrected using the proposed method. Through comparing the measuring precision before and after error-correction, the results indicate that this correction method can improve photoelectrical theodolite's measuring precision from about 15″ to less than 5″;that is to say the correction effect is obvious enough to prove that the method has achieved the expectant purpose. |
