Customized cartoon character modeling method and device, storage medium and computer equipment

According to the customized cartoon character modeling method and device, the storage medium and the computer equipment provided by the invention, firstly, the character LoRA model is generated based on the customized character video so as to learn character image features; embedding a character LoRA model into an initial image rendering model in which a normal LoRA model used for extracting character texture features and a cartoon style LoRA model used for generating character cartoon style features are embedded in advance to generate a target image rendering model; therefore, after the three-dimensional character model is constructed according to the character video and the rendered character image of the three-dimensional character model is obtained through rendering, the rendered character image is converted into the fusion feature value hiding the image feature, the surface texture feature and the cartoon style feature by using the target image rendering model; and performing parameter optimization on th
