Research situation at home and abroad is described in detail about simplification methods of point cloud data. After analyzing the advantages and disadvantages of existing algorithms, an improved algorithm, a method combining with deviation parameters and allowed angles to simply mass cloud data, is proposed from several aspects of complexity, required time and memory space. The experiments show that the simplified point cloud have a great relationship with the selected tolerance value. And the point cloud after simplification has advantages of high reservation of curve and surface reconstruction perfectly, which is reserved enough data. The proposed simplification algorithm is an effective and practical method.

3D Information

In order to realize the 3D reconstruction of stamping parts surface, this paper based on binocular stereo vision principle firstly introduces the model of the binocular cameras. Internal and external parameters of camera can be obtained by binocular calibration, taking the printed circle grid centers which are on the stamping parts as feature points, and then using the disparity image obtained by HALCON to reconstruct 3D information of the feature points. Finally, use Matlab to plot out the scatter diagram of feature points and the fitting curved surface diagram.
