Abstract

The invention provides a virtual dressing image generation method and system. The method comprises the steps of offline preprocessing and online operation, wherein offline preprocessing comprises thesteps of standard body material treatment, predefined grid design and production, determination of a translational relation from body type semantic parameters to grid control parameters and clothing image material treatment; and online operation comprises the steps of acquiring user data, calculating the grid control parameters, reading a body image and a clothing image, calculating a transformedgrid and rendering a dressing image. Through the generation method and system, quick transformation and clothing change are realized; synchronous transformation of the body image and the clothing image is realized; through the method of changing a predefined grid model, a fitting image is controlled and optimized conveniently; and one set of parametric grid system can be suitable for clothes of different shapes and texture. Besides, the method and system are suitable for clothing, shoes, accessories and images not shot realistically.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a method and system for virtual dressing images. Background technique [0002] With the development of information processing technologies such as computer graphics, many schemes that can realize virtual try-on have been developed. Through the virtual try-on system, users do not need to actually put on clothes, but only need to provide their images to the virtual try-on system to see the effect of the virtual try-on. This kind of virtual try-on system has a wide range of applications. For example, designers can use the virtual try-on system to assist clothing design. With the development of network technology, for ordinary users, this virtual try-on system is especially suitable for Online interactive systems such as online shopping and virtual communities. [0003] The existing virtual try-on can be mainly divided into two technical realization paths: two-dimensional and three...
