2-D Coordinate Transformation Based on Centre of Gravity Datum

Abstract:

2-D Coordinate transformation between different coordinate system including four parameters: two translations, one rotation, and one scale factor parameter. Because of ill-condition matrix, the common points’ little errors may cause big fluctuation of parameters’ results, which cause the four transformation parameters unreliable. Consider the comparability between coordinate transformation model and centre of gravity datum of free net adjustment, may eliminate the two translation parameters by auxiliary gravity datum condition. This article validate this method with instance.
