In order to filter out the noise points of the spine 3D model effectively,a denoising and spreading method for spine 3D model based on bilateral filter operator was proposed.The bilateral filter operator is used to extract the contours of the 3D model,design and improve the adaptive diffusion coefficient,in order to better optimize the control of the entire diffusion process.The discrete iterative equation is established and the iterative stop criterion is designed so that the iteration is stopped when the de-noising effect is optimal.Compared with classical methods such as approximate diffusion model method,the proposed method achieves good filtering effect in solving the denoising method,which is much better than the traditional filtering algorithm.
