Abstract

The invention discloses a point cloud data three-dimensional visualization rendering method and calculation method, and particularly comprises the following steps: S1, generating point cloud data witha standardized definition format through a conversion means without excluding other data, and relates to the technical field of point cloud data three-dimensional visualization. The method comprisesthe following steps of after normalizing and classifying data, performing point cloud rendering; performing vertex rendering, mapping rendering based on a three-dimensional grid, grid reconstruction rendering based on a triangulation algorithm, point cloud motion animation and point cloud particle animation. Multiple rendering algorithms of point cloud data are realized, rendering modes and effects of algorithms are different, the algorithms have different application directions, the method can supplement each other. Operation is more reliable, the rapid rendering of the point cloud data is realized through an efficient algorithm, and the rendering time of more than ten minutes is reduced to several minutes or dozens of seconds.

Description

technical field [0001] The invention relates to the technical field of three-dimensional visualization of point cloud data, in particular to a three-dimensional visualization rendering method and calculation method of point cloud data. Background technique [0002] In recent years, scanning technologies such as 3D scanning technology have made breakthroughs in hardware and made great progress in practicality, and have been more and more applied to actual production. In many scenarios, a large number of sensors for collecting data are deployed. In some scientific research projects, such as optics, acoustics, mechanics and electromagnetic analysis, many algorithm software generate a large amount of data through complex calculations, such as finite element analysis. In the field, some physical inspections can also obtain a large amount of data, and then perform image presentation based on algorithms. Many of these data are point cloud data based on three-dimensional space nodes...
