AI Technical Summary

Technical Problem

Existing technologies lack geographical and hydrological constraints, have insufficient authenticity and spatial correlation in the restoration of historical water culture images, and have inconsistent restoration systems, making it difficult to achieve high-precision restoration and digital protection.

Method used

By constructing a digital twin watershed model that integrates the basic geographic layer, the hydrological dynamic layer, and the water culture element layer, and combining it with historical image feature sets, the model restores the geometric structure of incomplete areas and enhances the texture details of blurred areas, and establishes a dynamic update mechanism.

Benefits of technology

It achieves a high degree of integration between historical images and historical water culture scenes, enhances the authenticity and accuracy of the spatial geography, historical hydrology and cultural elements of the restoration results, and forms an integrated technical process that is suitable for the digital protection and living inheritance of water cultural heritage.

Abstract

This invention provides a method for modeling and restoring historical water culture images, comprising: collecting multi-source data of a target watershed; constructing a basic geographic layer based on watershed geospatial data; constructing a hydrological dynamic layer based on historical hydrological records; constructing a water culture element layer based on the characteristics of ancient water conservancy projects and ancient buildings; and generating a digital twin watershed model; extracting image features from historical image data to construct a historical image feature set; restoring the geometric structure of incomplete areas in historical image data and enhancing the texture details of blurred areas in historical image data to generate restored historical images; associating and storing the restored historical images with the digital twin watershed model, and establishing a dynamic update mechanism based on new data input; this invention aims to solve the problems of insufficient geographic and hydrological constraints, inadequate authenticity and spatial correlation, and inconsistent restoration systems in existing technologies for historical image restoration, and to achieve high-precision restoration and digital protection and inheritance of historical water culture images.
