3D digital human generation method based on AIGC

The invention relates to the technical field of virtual digital humans, in particular to an AIGC-based 3D digital human generation method, which comprises the steps of data collection, data preprocessing, feature extraction, model generation, texture mapping, animation generation, model presentation, data transmission, data adjustment and data generation. Establishing coordinates for the generated 3D digital person, performing superposition comparison on a trajectory curve of a single joint of the 3D digital person in the coordinates and a corresponding preset trajectory curve, determining whether the operation of the single joint meets a preset standard or not according to the obtained superposition ratio, and when the operation of the single joint is preliminarily judged not to meet the preset standard, determining whether the operation of the single joint meets the preset standard or not. According to the distance between the terminal point of the obtained trajectory curve of the single joint and the termi
