Abstract:To improve the efficiency of triangle mesh surface reconstruction in neural network, an improved Kohonen neural network is put forward, which combines Kohonen neural network and faintness clustering algo- rithm, and by which large scale scattered point clouds triangle mesh surface and vase surface reconstruction have been done. Characteristics comparison is carried out between the improved algorithm and general one, and the results show that the improved algorithm avoids repeat circulation in general algorithm, reduces calcu- lation time, improves the efficiency and rate of the triangle mesh surface reconstruction. Simulation reconstruc- tion result indicates that the improved arithmetic can realize sparse and dense triangle mesh surface reconstruc- tion and data condensation under preconditions with primary data characteristics. The improved arithmetic has fast network convergence speed
