Problems solved by technology

[0003] However, most of the existing shoe last model reverse reconstruction file formats are point cloud models and NURBS surface models generated by the boundary blending method or facet feature method. Multiple redundant points, large storage space, difficult data management and analysis, which is not conducive to real-time processing of models

Abstract

The invention relates to a method and a system for processing a reconstructed foot triangular mesh model. The method comprises the following steps: performing triangulation and optimization on a processed point cloud model, performing triangulation on the point cloud model, preserving point cloud data while increasing a topological relationship between the point clouds; then using a surface deformation technology based on thin plate splines to compress a three-dimensional mesh sequence, and performing three-dimensional reconstruction by a MC algorithm; finally, detecting holes, and refining the model is refined by filling the holes. The system comprises an arithmetic unit, a reconstruction unit and a processing unit.

Description

Technical field [0001] The invention relates to a shoe last model construction technology, in particular to a method and system for reconstructing a triangular mesh model of the foot. Background technique [0002] Human feet are prone to deformation and difficult to stay at rest. If you use a contact measuring device to obtain the point cloud data of the foot, the probe of the measuring device will squeeze the surface of the foot during the measurement process, causing the shape of the foot to be deformed. The damage to the human foot also causes some errors in the point cloud of the human foot obtained by the measurement. Moreover, the use of contact measurement equipment requires the human foot to always be in a certain position, and the equipment needs to be fixed on the workbench. When measuring, the human foot also needs to move with the workbench. It is difficult for the human foot to meet these requirements. As a result, many foot feature parameters and some complex curve...
