基准误差修正的弯管测量方法

Elbow Pipe Measuring Method by Datum Error Correction

在空间弯管的测量中,为了减少坐标系的基准误差对测量结果的影响,首先对弯管的基准误差进行分类讨论,根据坐标系建立的步骤,针对不同的基准误差找出相应的修正方法,最后通过某排气管的实例测量来进行验证,证明了基准误差修正后的坐标系可以提高测量结果的准确性。

During the measurement of space elbow pipe,in order to reduce the influence of datum error of coordinate system on measurement results,firstly the datum error of elbow is classified and discussed,and then find the correction methods for different datum errors according to the steps for setting up the coordinate system.An example of an exhaust pipe is finally used to verify the results,which is proved that the coordinate system with datum error corrected can improve the accuracy of measurement results.
