Abstract

The invention discloses a point cloud mesh refinement system and a point cloud mesh refinement method, which are applied to a computer device. The method comprises steps: a point cloud for a target product is acquired, and triangulation is carried out on the point cloud for the target product; triangular meshes in need of refinement are selected, and a needed iteration number N is inputted according to the precision requirement for the mesh refinement; according to the shape and the position of each triangular mesh, a mesh subdivision method is used for subdividing each triangular mesh into different types; a loop triangular mesh subdivision algorithm is used for carrying out N times of refinement processing on the triangular meshes of different types, and triangular meshes after refinement are obtained; point cloud smoothing processing is carried out on the triangular meshes after refinement, a three-dimensional mesh model for the target product is obtained, and the three-dimensional mesh model for the target product is displayed on a display device. When the system and the method of the invention are executed, quick and effective refinement can be carried out on the point cloud mesh of the target product, the model features of the target product can be kept, and a refiner and smoother three-dimensional mesh model for the target product can be acquired.

Description

technical field [0001] The invention relates to a point cloud grid processing system and method, in particular to a point cloud grid refinement system and method. Background technique [0002] In the point cloud mesh processing, obtaining the meshed point cloud from the scanner, and then processing the mesh to obtain the product CAD data is an important step in product inspection and reverse engineering. Because the point cloud acquired by the scanner is often not fine enough, mesh fineness is an important part of mesh processing. In the currently released grid hole repairing system, the grid refinement algorithm is complicated and the calculation speed is slow. Mesh fineness cannot be widely used, complex objects are easy to change the shape of the object, and the fine effect is not good. After fineness, the details of the object cannot be highlighted, and a smoother model cannot be obtained. Contents of the invention [0003] In view of the above, it is necessary to pr...
