Description

technical field [0001] The invention relates to the technical field of three-dimensional mesh deformation, in particular to a clothing deformation method based on Laplace deformation of the human body. Background technique [0002] The existing virtual fitting applications mainly include virtual fitting websites, virtual fitting mirrors and virtual fitting systems on mobile terminals. Among them, the more common is the three-dimensional virtual fitting mirror. The "Fitting Mirror" developed by AR DOOR Technology Company in Russia and the "Active Lab" fully interactive virtual fitting mirror invented by Digital Fashion Company in Japan are typical cases of the practical application of virtual fitting mirrors. [0003] The advantage of the virtual fitting website is that the operation is simple and the equipment requirements are low; poor. [0004] The working principle of the virtual fitting mirror is to obtain the user's image, body dimension and motion information throug...
