acquired idea
4.Aimed at the limitation of the traditional three points locating method in measuring data registration, a new idea applied the similarity theory to pattern recognition to the registration of measuring data under different viewpoints is presented, where the curvature extremum points in data superposition area are searched with the gradient method, then the feature points in the curvature extremum points according to the principle of gay similitude in pattern recognition are acquired, and the measuring data registration is carried out at the corresponding feature points.
