Abstract

The invention discloses a triangular mesh filtering method based on a Laplace operator and a terminal device. The method comprises: dividing the neighborhood of each vertex into two parts, then calculating the Laplace operator of each field half window, and updating the vertexes according to the calculated Laplace operators, so that sharp features on the triangular grids can be recovered, and thegrids can be prevented from turning over. In addition, the vertex updating method can quickly obtain the filtered triangular mesh model, only one iteration number parameter exists, and the method is simple and easy to use.

Description

[0001] technology neighborhood [0002] The invention relates to the technical field of image processing, in particular to a Laplacian-based triangular grid filtering method and terminal equipment. Background technique [0003] With the advancement of sensor technology, 3D scanning technology has been widely used in artificial intelligence, 3D reconstruction, VR / AR and other fields. Generally, the initial point cloud storage capacity obtained by scanning is huge, and it is not convenient for algorithm processing. After surface reconstruction The obtained triangular mesh model is the simplest and most commonly used data. However, during the scanning and reconstruction process, the triangular mesh model will inevitably be polluted by noise, which will reduce the visual quality of the triangular mesh model itself, and will also affect the subsequent mesh processing effect, thus affecting the quality of the 3D scanned image. Effect. Contents of the invention [0004] In view o...
