Method and device for denoising three-dimensional image data, and storage medium

The invention discloses a method and device for denoising three-dimensional image data and a storage medium. The method comprises the following steps: acquiring three-dimensional image data and determining a corresponding triangulation network based on the three-dimensional image data; calculating a cut image according to the triangulation network and cutting along the cut image to obtain a topological disc related to the three-dimensional image data; calculating the shortest path mapping of the topological disc mapped to the triangulation network; cutting the triangulation network by using the shortest path mapping to obtain a cutting boundary; and executing topological hole filling operation for filling the cut triangulation network based on the cutting boundary so as to realize denoising of the three-dimensional image data. By means of the scheme, the ring handle in the three-dimensional image data is efficiently eliminated, and topological denoising is achieved. 本申请公开了一种用于对三维图像数据进行去噪的方法、设备和存储介质。所述方法包括：获取三
