In photogrammetric surveying, the algorithmic finding for coordination on earth with picpointed coordination involves nonlinear transfer of coordination among coordinate systems. Theoretical arithmetic is generally carried out under the supposition that the angle of rotation is at minimum. This paper put forward a nonlinear algorithm of coordinate rotation transfer, which is of least squares and PLOT 3D. Compared with other general methods at present, the algorithmic search for the best estimated value of seven-parameter through the minimum multivariate function is more convenient, efficient a...
