Abstract
The embodiments of the present disclosure disclose a three-dimensional model's spherical expression calculation method. A specific implementation of the method includes: processing an input three-dimensional model into a dense point cloud model; inputting the dense point cloud model to a multi-level feature extraction module, extracting high-dimensional feature vectors of different abstract levels; inputting the high-dimensional feature vectors, template ball point cloud and abstract preprocessed point cloud model to a point cloud deformation reconstruction module to obtain a deformed reconstruction point cloud model; extracting multi-stage deformation reconstruction process information, combining the multi-stage deformation reconstruction process information with the template ball point cloud to together form complete information describing the three-dimensional model; obtaining a density correspondence from the three-dimensional model to the template ball point cloud and a density correspondence between different three-dimensional models. This implementation does not require time-consuming and labor-intensive manual annotations, improving the efficiency of characterization learning.
