摘要
本文分析了特征点应满足的几种条件,给出了一次范数最小(L1)法、最小二乘(LS)法以及粗差探测(D-S)法进行特征点粗差定位方法,并以模拟实例为例对它们进行了比较。
This paper analyses several conditions which feature point should meet with.The feature point gross error can be located with least absolut sum method,least square method and gross error detection. They are compared by using analogous examples,and some significance conclusions are obtained lastly.
