| Abstract: | A simple correspondence approach in camera calibration is proposed based on Delaunay triangulation to automatically match the image coordinates with the world coordinates for feature points with regular grid network structure.The topological structure of the feature points was generated by Delaunay triangulation and pretreatment which removes the redundant triangles.The correspondence between the image coordinates and world coordinates of feature points was implemented by using the topological s... |
