摘要: |
在平差模型中引入补偿参数,并顾及起始坐标(高程)的验后权和未知数的先验权后,按最小范数最小二乘原理进行平差,可以得到与经典平差等价的平差公式,精度高于一些其它平差方法,而且不存在未知数初值的合理选择和起始数据产生改正值的问题。 |

QUASI CLASSICAL ADJUSTMENT |

Abstract: |
Firstly introduces a compensative parameters into the adjustment function model.Then under V~T pv=min and x~Tp x=min condition,derives an adjustment formula.According to this form'ala to adjust the network,the accuracy of con- trol points is higher than others and the adjusted value is equivalent with the classical adjustment. |
Key words: priori weight posteriori weight minimum norm compensative parameters |
