3D Reconstruction Of Human Body Surface Oriented To Individualized Garment Customization

There are continuously increasing demands for comfortable and individualized clothing, also the requirement of special body types. In order to meet the need of people and solve the problem of batch production, adapting to the developing tendency of production mode, the technology of 3D human body reconstruction oriented to individualized garment customization is studied in this paper. The method of NURBS surface rebuilding is proposed to realize the reconstruction from scattered data of human body, which combines the flexibility of triangle meshes and the versatility of NURBS, satisfying the need of local modification. The main works are summarized as follows:1. A triangle growing algorithm with constraints is present to triangulate 3D scattered data. This algorithm takes the threshold distance and the visibility of point to edge, deleting closed points role and LOP criteria as constrained conditions to reduce the searching area and improve the quality of the mesh. It establishes the triangular topology and receives orderly data.2. An improved edge-collapse algorithm keeping original points is put forward to simplify triangular mesh. Then the maximum weight matching algorithm which takes the quadrangle deformation factor as the weight implements quadrilateral region partition, which meets the requirement of data distribution of later surface recovery.3. NURBS method is applied to reconstruct surface. The algorithm of NURBS surface reconstruction is implemented. The main steps include building up Coons base plane on the quadrilateral region, parameterizing data, computing control points and interpolating NURBS surface.4. The visualization of 3D mannequin is realized by OpenGL technology and interface program of NURBS curve and surface based on VC++ environment.
