| Abstract: | Plane similar conversionis based on least squares estimation. If there are some errors in the surveying datum which are used for modeling, then the robustness of plane similar conversion model will not be guaranteed. Because of brainpower and robustness for parameter detecting, principle of information diffusion is naturally used for exploring the reliable model. In this paper, we deduce a series of statistics for scale and circumrotation angle during the course of modeling, bring forward a kind of reasonable method to judge model reliability by using approximate t-test, and last, we also demostrate the manipulation process of model reliability analysis by the example of Xiaodongjiang GPS metamorphose monitoring network. |
