The invention relates to the technical field of computers, in particular to a multi-mode-based three-dimensional model editing method and device, equipment and a medium. The method comprises the following steps: acquiring a multi-
modal fusion image personalized generation method and a source three-dimensional model; obtaining a personalized
image generation network corresponding to the source three-dimensional model, and training the personalized
image generation network; based on the
reference image list and the corresponding text description, multi-
modal embedded information is obtained after fusion; taking the trained personalized
image generation network as a skeleton, and adding a multi-
personalized learning module to obtain a multi-personalized
image editing network; and editing the source three-dimensional scene image according to the multi-
modal embedded information by using a multi-personalized
image editing network to obtain a single-view-angle edited image. The multi-mode embedded information generated by the method allows a user to input prompt information of
multiple modes such as texts, images, sketches and the like, complementarity of prompt of each mode is mined, so that
controllability of editing is improved, and high-quality three-dimensional model editing is realized.
