Abstract: Inversion of parameter based on total least squares（TLS） is investigated.Strain parameters TLS inversion method is deduced,and the errors of distance changes and azimuthal angles are considered.The method of precision evaluation is given.Through the examples,the strain parameters based on total least squares are more reasonable.If there are constant columns in the coefficient matrix,they must be removalled.Otherwise,the obtained parameters are wrong using the TLS.Because the errors are distribut... More
