Three-dimensional model retrieval method and device and computer readable storage medium

The invention discloses a three-dimensional model retrieval method and device and a computer readable storage medium. The method comprises the following steps: acquiring a three-dimensional model file to be subjected to model retrieval; performing feature extraction on the three-dimensional model file based on a pre-trained artificial intelligence model to obtain a feature vector of the three-dimensional model file; and according to the feature vector, performing model retrieval in a three-dimensional model database by adopting a feature retrieval engine based on a similarity search class library to obtain a first preset number of target three-dimensional models with the highest similarity. According to the method, the feature vector of the three-dimensional model file to be subjected to model retrieval is extracted through the pre-trained artificial intelligence model, and the model retrieval is performed in the three-dimensional model database by adopting the feature retrieval engine based on the similarity
