AI Technical Summary

Technical Problem

Existing methods for assessing urban building safety mainly rely on manual point-based observations, which are inefficient, unable to proactively predict structural safety hazards, and insufficient in identifying risks in the surrounding environment.

Method used

By acquiring synthetic aperture radar (SAR) images, optical remote sensing images, hyperspectral images, and topographic data, the system automatically identifies changes in building spatial morphology and generates change parameters; it uses SAR images to monitor building displacement changes and generates settlement parameters; it identifies the spatial relationship between the building and surrounding environmental risk bodies and generates external impact parameters; and finally, it generates safety assessment results based on these parameters and a preset model.

Benefits of technology

It has achieved automation and efficiency in urban building safety assessment, enabling large-scale monitoring of building displacement changes and identification of surrounding environmental risks, thus improving the efficiency and accuracy of safety assessment.
