Study On 3D Body Reshape Based On Personalized MTM

Since the rapid prevalence of the internet, retail trade presents itself with bran-new business model. Selling online has been accepted by more and more consumers, especially in dressing product selling, of which the sale volume has been increasing continuously. But during the shopping online, consumers are not be able to try on the clothes to confirm the size, style and feeling, meanwhile, due to diversity of body type, customers maybe hesitated. Consequently, study on three-dimensional body modeling based on customers' figure will be favorable for online sales.This paper is a sub-topic of digital apparel, The main tasks are as follows:(1) Extract the contour of the body images, and extract the human body feature points from the contour image, lay the foundation for the realization of the deformation method use the body parameter or the body contour image.(2) Study and implement to read and render OBJ human body model exported from Poser under C# platform, define and extract the feature points, feature sections on the human body model, thus achieved a parametric deformation of the human body. This method is quite easy to get control parameters, can be used on the dressing system on network, where we can use the parameters input by users to deform body models.(3) At present the body characteristic parameters obtained from the body image are limited and can not be guaranteed for their accuracy. Thus the three-dimensional reconstruction of the human body with these information can not be trusted completely. In response to this problem, this paper presents a method of extracting human body contour from the orthogonal body image and modifying the body model with the outline information directly. This method avoids the transition from image information to the parameters and eliminate the errors, the generated three-dimensional human body model can reproduce the true face of human body more faithfully, and amend the problem of model can not truly represents the human users in the current fitting system effectively.(4) We design and realize the system of 3D virtual human body, including implementation of global blue print of design with the system framework, internal programme and module,As one of the key technologies in P-MTM, 3D human body modeling will promote the development of individual made to measure for garniture.
