Three-dimensional Virtual Fitting System Based On Somantosensory Device

With the increase in the scale of clothing e-commerce transactions and the development of somatosensory interaction technology,the vitual fitting system has received more extensive attention with more research on it being carried out.The virtual fitting technique makes it possible to check the dressing effect without actually trying clothes on,which can make up for the lack of dressing experience in the online clothing purchasing process.This study completed the construction of a three-dimensional virtual fitting system based on the somatosensory interaction device.Compared with a fitting system based on two-dimensional image stitching,the three-dimensional virtual fitting system does not need to produce clothes pictures at all angles,and has more realistic dynamic effects of clothing fabric.This system completes the posture adjustment of clothes based on the skeleton system,and optimizes the display of the close-fitting effects,which increases the sense of authenticity of the fitting results.The research content of this topic is as follows:First of all,this paper studies the skeletal estimation algorithm of the clothes-dresser with the somatosensory device,which lays the foundation for the subsequent attitude matching based on the humanoid skeleton system.In addition,according to the characteristics of clothing fabric,the simulation model of fabric is analyzed and studied,and the dynamic analysis of fabric is completed.For the matching problem between clothing and clothes-dresser,this paper studies the mesh skinning algorithm and makes improvement to the defects of the traditional methods.It adds a skeleton system corresponding to the clothes-dresser for the clothing model,and completes the scaling and rotation of each skeleton based on the relationship between joints,which makes the clothing match the posture of the clothes-dresser in the screen space.In addition,a judgment method based on depth comparison is proposed to correct the correct the undesirable concealment effect of certain clothes in the process of fitting.Furthermore,in order to complete the simulation of the close-fitting effect of the clothes,this paper firstly optimizes the mesh quality difference caused by the different standards of model preparation.On this basis,the surface of the clothes-dresser and the surface of the clothes mesh model are divided into corresponding regions using the specific joints,and the spatial positions correction of the mass points in the entire region are then adjusted in a line-by-line sequence,so as to improve the wearing effect.Finally,the architecture design and implementation of the system are completed under the Unity3 D engine.In order to avoid the complexity of operation based on additional hardware devices and the lack of accuracy of interaction based on voice instructions,the paper completes the design of display interfaces and interaction strategies based on user gesture operations.Through the stretching and closing of the hand gesture,the release and clicking of the left mouse button are simulated,thereby completing the selection operation of the clothing.In addition,the system will conduct corresponding instructions and prompts based on the location of the user.
