This application discloses an image processing method and related apparatus. Through a feature extraction module in the image processing model, image features representing buildings can be extracted from the input image. By using one or more modules in the structural information modules corresponding to multiple building structural dimensions within the image processing model, structural information recognition can be performed on the image features in parallel, obtaining the structural information of the building corresponding to each of these modules' building structural dimensions. This structural information can represent the building's structure from multiple structural dimensions, thus providing a more comprehensive and accurate understanding of the building's structure. Furthermore, since the structural information across multiple building structural dimensions is based on the same image feature analysis, this structural information can more accurately represent the structural characteristics of the same building across multiple structural dimensions, achieving more accurate and comprehensive automated analysis of structural information.
