The Design And Implementation Of Virtual Accessories Fitting System Based On Polymer Dispersed Liquid Crystals

With the application of augmented reality technology in the clothing retail industry,more and more virtual fitting systems have been developed.It can superimpose 3D vitual products on the user's dynamic images to show the lifelike fitting effect.The virtual fitting system based on augmented reality technology can not only help e-commerce companies to solve the problem that consumers cannot try on product online,but also solve the problem of long waiting time outside the fitting room in store.At the same time,with the rapid development of deep learning,more and more manufacturers apply image recognition technology to the problem of clothing recognition to improve user experience.The application of costume recognition technology to the virtual fitting system can improve the fitting experience of users and the recommendation efficiency of clothing and accessories.In the selection of the screen,because the polymer dispersed liquid crystals can switch transparent state to opaque state,based on polymer dispersed liquid crystals than LED screen overcomes the problem of view shade,can solve the problem of using LED display screen in the business window shade shop goods,therefore,using polymer dispersed liquid crystals with projection system can be deployed to the commercial window to attract customers.Virtual accessories fitting system using augmented reality technology and deep learning technology combined with polymer dispersed liquid crystals technology applied to commercial Windows can promote the development of the clothing and accessories retail industry.In this paper,according to the needs of users in vitual trying on,following the design method of easy to interaction,according to the specifications of software engineering,the virtual accessories fitting system based on polymer dispersed liquid crystals is analyzed in detail,and the system is designed in detail according to the functional requirements and non-functional requirements.According to the architecture design and detailed design to complete the implementation of the system and unit test work.In the design of the system,a variety of key technologies are used to improve the user experience.In order to enhance the user's sense of reality,a real-time 3d human pose estimation algorithm is developed.In order to users easy to interact with the system,the system adds the function of choosing accessories using mobile devices;In order to improve the rendering effect of handbag model,the system uses Unity3D as the rendering engine;In order to deploy the system in the commercial window,the system uses polymer dispersed liquid crystals as the display.The system includes virtual handbag model superposition,virtual handbag recommendation,vitual handbag selection and other main functions.In terms of development tools,the system uses game de'velopment engine Unity3D,combines Maya modeling tool,deep learning algorithm and Web development tool to realize the recommending and fitting of accessories.The system realizes the development of user pose estimation and user clothing style recognition algorithm,and applicate the system to polymer dispersed liquid crystals.According to the user clothing style,superimpose the 3D virtual accessories onto the user image,and provide online accessories selection service.In this paper,a real-time virtual accessories fitting system with immersion and realism is realized,which has positive significance to the development of clothing and luggage industry.
