Embodiment Construction

[0029] Build the clothing mechanics cloth model:

[0030] 1. Establish a classic grid model according to the physical connection structure of the cloth particles. The vertex of each grid is the particle of the cloth, each particle has force and direction, and the edge is the elastic value of the cloth; establish a mechanical model for each particle, considering The constraints of gravity and contact force are used to solve the grid shape after the collision between the cloth and the human body, and between the cloth and the cloth at each step. The mesh model of the entire clothing is stored in the data structure of the AABB tree, that is, the Axis-Aligned Bounding Box.

[0031]2. Triangulate the cloth mesh model for surface smoothing. The surface is smoothed through interpolation and relaxation iterations, so that the simulated folds are regular and uniform, and can effectively avoid concave defects at the joint bends.

[0032] 3. Adopt a global-local hybrid strategy. Local ...

Abstract

The invention discloses a three-dimensional real human body online virtual fitting system. A topological structure of cloth particles is simulated by clothing mechanical cloth models, by adding of connecting sides, a triangular mesh is constructed by the cloth models, the cloth is seen as a set of a group of discrete particles, and mechanical models are established for the particles on the basis of consideration on a constraint force of cloth; bending and wrinkling behaviors of the cloth are realized by continuous movement generated by interaction forces of the particles, characterized bendingdeformation behaviors of cloth which is made of different materials or has different precisions are simulated, therefore, the reality of the bending deformation effect is improved, and a user can rotate circularly in front of a camera or walk to appreciate fitting effects at different angles, and can feel garment material quality, drooping style, wrinkles and fitting degree; and moreover, by recognition of human intention, the wearing effect after the user does different actions is achieved in real time. In addition, the system can be realized by only one camera.

Description

technical field [0001] The invention relates to the field of digital clothing, three-dimensional model technology, especially the online three-dimensional virtual fitting technology and system method for real people. Background technique [0002] At present, some domestic research institutions have proposed different virtual fitting concepts, and some fitting products have entered the commercial market or are in the stage of trial application. The earliest virtual fitting was achieved by standing in front of a big screen with the help of AR technology. These can only be seen in front of the fitting effect, which is a static fitting. At this stage, some dynamic fitting applications have appeared, which allow customers to turn left and right to see the fitting effect, such as VIPodium. Taobao’s 3D fitting room is better in China. The difference between it and JD.com and Uniqlo’s 3D fitting room is that it allows consumers to move around dynamically while trying on clothes, an...
