摘要:In space resection computing,the error equations are based on the collinearity equations. Because the coordinates of the ground point and the image point all exist errors. So we use the Total Least Squares (TLS) method. The method of Total Least Squares is one of several linear parameter estimation techniques that have been devised to compensate for data errors. Furthermore, TLS is the method of fitting that is appropriate when there are errors in both the observation vector b and the variable matrix A. So it can establish a more practical and suitable model so-called Error-in -Variables model. On the base of this model, the errors in the observation vector b (e) and the variable matrix A (E A ) can be corrected at the same time
