Description

technical field [0001] The invention relates to the field of computer vision, in particular to a method and system for virtual fitting of clothes based on collision bodies. Background technique [0002] The fitting facilities are generally fitting mirrors, which can only see the front and partial mirror images, but cannot see the suitability of the clothes and body shape behind and during walking, and cannot retain images of the fitting process. [0003] With the development of virtual reality technology, many solutions that can realize virtual fitting have been developed. Through the virtual fitting system, users do not have to actually put on clothes, but only need to provide their own information such as body shape to the virtual fitting system, and then they can see the effect of fitting in the fitting environment. The virtual fitting system constructs a three-dimensional human body model consistent with the user according to the user's real body shape coefficient, so t...

Problems solved by technology

There are two existing collision detection methods based on virtual reality technology. One is to simulate the collision body model of the human body with a capsule body. Although the capsule body simulation is very efficient in the physical simulation of virtual fitting in the fitting system, However, since the human body model has limbs and torso, it is not just a capsule shape, so based on this method of collision detection, the human body model cannot fully fit the clothes during the fitting process, resulting in poor visual experience of virtual fitting

Another method is to use the enveloping body of the triangular surface to physically simulate the human body and the clothing. This method can fit the human body model and the clothing well during the virtual fitting, but the calculation based on the triangular surface technology If the amount is too large, the simulation efficiency is very low. Therefore, the human body cannot make large-scale movements (such as raising hands, turning around, etc.) during virtual fitting. Show the effect of virtual fitting in real time, thus affecting the fitting experience
