Abstract

The present invention relates to a 3D model topology mapping method based on deformation driving. The method comprises the following steps: 1) extracting a model file; building a corresponding 3D model according to the model file; 3) searching a mapping state through a heuristic algorithm, wherein the search process is driven by the mapping energy; 4) selecting the optimal mapping state according to the search result; 5) realizing the visualization of the corresponding source model and the target model according to the optimal mapping state; and 6) outputting a result file. Compared to the prior art, the 3D model topology mapping method based on deformation driving is high in efficiency and high in quality of the return result, etc.

Description

technical field [0001] The technical field of graphic analysis of the present invention relates to a 3D model mapping method, in particular to a deformation-driven 3D model topology mapping method, which is a component-level model mapping method that can handle geometric changes and topology changes. Background technique [0002] Model mapping algorithm is a basic problem in graphics, and it is widely used in various fields, such as object recognition, clustering, model deformation, static modeling, etc. For a long time, the model mapping algorithm has attracted people's attention, and a large number of related researches have emerged. Previously, most of the classic related algorithms for model mapping problems focused on models with specific geometric requirements, such as "Robust global registration" by GELFAND et al., "Deformation-driven shape correspondence" by Zhang et al., and "Deformation-driven shape correspondence" by Huang et al. Non-rigid registration under isom...
