Two-step Method to Detect Unstable Known-points for Free Stationing

doi:10.13474/j.cnki.11-2246.2017.0109

Abstract

Abstract: An analysis method to detect unstable known-points for free stationing is researched in the paper. Coordinate system transformation is used to get the known points' displacements. Then the stability of each known point is obtained based on these displacements. To solve the accurate transformation relation, the RANSAC Algorithm is used to calculate initial value, final result is obtained by iteration. The validity of this method is verified by the field and simulation test.

Key words: free stationing, availability of known-point, robust estimation, RANSAC
