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.

This invention discloses a method for estimating the quantity of bridge engineering projects based on a GIS system, belonging to the field of bridge engineering technology. When calculating bridge engineering costs, this invention obtains a table of bridge structure information at work sites from the GIS system; determines the structural type of the bridge engineering project at the work site based on the table; determines the corresponding structural dimension parameters based on the structural type; calculates a data table of structural quantities corresponding to the structural type of the bridge engineering project at the work site based on the structural quantity parameters; generates a summary table of bridge quantities at the work site based on the structural quantity data table; and queries a code table of bridge engineering structural quantity information based on the summary table to determine the structural quantity code. A cost quota is then obtained to calculate the bridge engineering cost. This method allows for direct division of bridge engineering structures using the GIS system, thereby enabling rapid and accurate calculation of the quantities of engineering works in bridge projects and improving the accuracy of engineering cost calculation.
