The Design And Implementation Of Virtual Fitting System Based On Kinect

With the development of the Internet era and human-computer interaction technology,interactive system based on body feeling received widespread attention and research.Body feeling virtual fitting system has advantages of easily operation,naturally interacting and provides users with better shop experience.Previous virtual fitting system mostly built virtual user model through manual inputting parameters by users,and then according to the user model to implement virtual fitting,the sense of the user and the fitting effect are not strong.In terms of clothing simulation,use simple 2D textures of clothing to simulate the way of the fitting has limitation for user in the process of action and body angle,it couldn't show the fitting effect very well.The way to make 3D models for clothes need to make model for every entity clothing,it is difficult to model and has high cost.System maintenance cost is also high,the production cycle is long,it can not used in practical project very well.This thesis designed and realized a set of virtual fitting system based on kinect,according to the above problem,this thesis made some new attempts.The main contents are as follows.1.Through cutting 2D clothing pictures in the joints of user,then according to the way of joining the user's bone joints together to improve the limitations when users are fitting,that users can make some actions in the fitting process.Besides,implementing the clothing graphics zooming in and out with user body moving and rotation transformation of partial clothing graphics according to the user body action,that improve the effect of the fitting.2.The perspective transformation algorithm is applied in the clothing images,and track user's bone joint points distance and depth value to calculate the turning angle,combination of the two to achieve the stereo effect in the process of the fitting clothes.3.Calling Kinect Tool Kit class libraries to capture the actions of body,get the skeleton data and hand contour information to realize the function of action recognition and gestures judging,including how to simulate the mouse to operate menu,body feeling press button to realize the button click event,hand grasping action recognition to realize the function of scrolling list,which improve human-computer interaction effect.The system fitting result test shows that the fitting system has a good fitting result,which could meet the basic requirements of users daily fitting.
