Virtual fitting model training method, virtual fitting method and related device

The invention provides a virtual fitting model training method, a virtual fitting method and a related device. A virtual fitting model comprises a first coding module, a second coding module, a third coding module and a decoding module, and the virtual fitting method comprises the steps that a three-dimensional body image of a target user is acquired; a clothes image and text description of the target clothes are obtained; the three-dimensional body image, the clothes image of the target clothes and the text description are input into a target virtual fitting model to obtain a target three-dimensional image of the target clothes worn by the target user, and the target virtual fitting model is obtained through training of a virtual fitting model training method. The target virtual fitting model can generate the fitting image which is vivid enough, the three-dimensional features of the fitting image are consistent with the three-dimensional features in the three-dimensional body sample image, and the clothes fe
