The method is selected, vision, GPS receiving signal strength of the feature points in the field (such as linear object intersections, independent features, etc.) is the best stone control points were measured and compared with theory and find out the coordinates of these points. If the results of the comparison exceed the nominal accuracy of the instrument, the conversion parameters or the problems that should be found should be recalculated.
