Spatial coordinate transformation considering known point errors
In order to improve the precision of space coordinate transformation,it is necessary to provide an accurate coordinate transformation model.In order to get an accurate space coordinate transformation model,the error of known points should be considered.This paper studied the space coordinate transformation model by considering the precision of known points.Using the method of comparison and simulation analysis,the paper carried out space coordinate transformation based on the simulation data by considering the precision of known points and ignoring the precision of known points.The analysis results show that the precision of the space coordinate transformation model considering the precision of known points is high.The results provide a scientific space coordinate transformation model for surveying and mapping production departments.
