Abstract


The virtual trial system of garments has three parts. Firstly, getting the three-dimensional human body information from stereo vision principle or customer, and building the personality model. Secondly, trying dress on the human model. There are a lot of clothing pictures, the customer could choose favorite one. Thirdly, showing fitting effect.With the increasing popularity of the Internet online sales have been more and more consumers accepted especially clothing products online sales growth in recent years. But, the customers can’t confirm the size, style and feel with fitting online. However, the current fitting platform online are static without dynamic display. Therefore, it’s very necessary to build up the virtual trial system of garments for dynamic display. Of course, the nature is of dynamic movement is human body skeleton’s movement.This paper is a sub-subject about the digital clothing study to obtain three-dimensional human body information by many means and build skeleton dynamic modeling. The mainly works as follows:(1) Based on automatic extraction human skeleton, setting up 3D body skeleton dynamic modeling. The joint angle and physical constraints are introduced, according to the characteristics of joint rotate to build the joint rotate model.(2) The conformal geometric algebra is introduced to describe the joint movements and estimate the 2D-3D gesture. Giving one part video, the human skeleton model simulates the movement of the video. Finally, compare the both means which are the conformal geometric algebra and space analytic geometry. The result turns out that the conformal geometric algebra method is more quick and efficient.(3) This paper designs and completes the 3D human virtual generate system and 3D human skeleton dynamic modeling, including the system framework of the overall design proposal, the internal programs and the realization of movement module.Finally, we make a summary to all the work, point out that binding skin based on the human skeleton and virtual trial system of garments need further in-depth research in the future.
