Research On 3D Human Body Reconstruction And Virtual Fitting System

Relying on the rapid development of the Internet,more and more people in the way to buy clothing has also undergone a change in thinking,from the traditional purchase of going to a brick and mortar store to try to buy the traditional way to expect to buy clothes online without leaving home.The biggest advantage of buying online is to save time and effort,but the problem lies in the suitability of the size of the clothes purchased.In order to meet the needs of users,more and more e-commerce platforms began to develop new technologies to solve the difficulties of consumers at home to buy the right size clothing,the premise is to obtain the relevant parameters of the consumer’s body to be able to customize clothing.At present,there are many body parameters measuring instruments on the market,but they are expensive,complicated to operate,and the biggest problem is that the equipment is huge and bulky,not suitable for personal operation at home.In order to solve all these problems,this paper proposes a new virtual fitting technology,firstly,by taking frontal as well as side photos of the human body for image based 3D human reconstruction,after getting the human body model,then modeling the garment,merging the garment model with the human body model,and completing the virtual fitting,it will be possible to achieve the effect of fitting the garment model that fits the size of the consumer.The main work of this paper is as follows.(1)The research of 3D human body reconstruction technology based on monocular camera.The front view as well as the side view of the human body are taken by the monocular camera,and the obtained 2D image is extracted for contour.The human body model from SCAPE database is contour extracted and transformed,input to the improved Goog Le Net neural network model for training,and the actual human body contour is input to the trained network model to obtain the shape parameters of the human body,and finally the parameters are applied to the standard model for deformation to obtain a personalized human body model.In this paper,a comparative analysis of the reconstructed models is also carried out.(2)Research on Simulation Design of clothing model and implementation of virtual fitting.In the part of garment customization,this paper uses the improved triangular mesh growth algorithm to mesh the set points,establishes the cloth model based on the mass spring model technology,solves the integral of the model through modeling and force analysis,and finally applies a fixed penalty force to virtual stitch the model,completing the combination of garment model and human model.Finally,this chapter completes the try on effect of different body types on the same clothing,which can reflect the customization of clothing model.(3)designed a virtual fitting system based on the design of unity 3D-based.In this paper,based on the design of system functional modules and overall architecture,the design and implementation of user login and registration module,photo reconstruction module and virtual fitting simulation module are completed.Customers can choose the clothes they are satisfied with to try on,and feel the effect of trying on clothes through 3D rotation and movement transformation,which basically meets the needs of customers and has good practical application value.
