Abstract

The invention discloses a data processing method and a data processing device used for removing voids in a grid model. The method comprises the following steps of determining the grid model, wherein the grid model comprises outer sides; the outer sides are sides only existing in a triangle in the grid model; the outer sides comprise a first outer side; the first outer side has a first endpoint and a second endpoint; the first endpoint is a non-multilateral point; judging whether the second endpoint is a multilateral point or not, wherein the multilateral point is an endpoint shared by more than two outer sides; if the second endpoint is the multilateral point, determining an endpoint topologically continuous with the second endpoint to be a third endpoint, wherein the third endpoint is the endpoint of a second outer side, and the second outer side and the first outer side share the second endpoint; executing void removal treatment: performing traversing on the endpoints of the outer sides contained by the grid model according to a topologically continuous direction to acquire singly connected voids in the grid model. Through the data processing method and the data processing device disclosed by the invention, the problem that the execution efficiency when the removal treatment is performed on the voids in the grid model is low is solved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data processing method and device for removing holes in grid models. Background technique [0002] With the continuous improvement of product iteration speed and individual requirements, product design requirements are becoming more and more rapid and accurate, so prototype-based modification design is widely used. Reverse engineering uses 3D scanning technology to obtain point cloud data of product prototypes, and further processing to obtain digital product grid models, which can greatly speed up the speed of modification design. [0003] However, in 3D scanning, due to equipment limitations or the characteristics of the product itself, the generated point cloud often cannot contain complete and continuous prototype features, resulting in a large number of holes in the subsequent mesh model. These holes have a great impact on the further modification design based on the mesh m...
