| Abstract: | Aiming at the coordinate transformation between two 2D coordinate systems,diffrient accuracies from diffrient models will be achieved.This paper utilized the program to compare the accuracy of four-parameter model,six-parameter model and second-degree polynomial model.Results from testing showed when reasonable choose transforming points,the accuracy of second-degree polynomial model is better than the accuracies of four-parameter model and six-parameter model in 2D coordinate transformation. |
