AI Technical Summary
Existing technologies cannot automatically obtain the precise coordinates of bridge defects in three-dimensional space, resulting in low bridge inspection efficiency and limited coverage, making it difficult to meet the requirements of refined management in modern bridge operation and maintenance.
By constructing a BIM model of multi-source bridge data, collecting image metadata and inputting it into the disease identification AI model, identifying the pixel coordinates of the disease area, and combining the relationship between pixel displacement and viewing angle change, adjusting the viewing angle of the shooting equipment, the disease can be automatically located and visualized in three-dimensional space.
It enables high-precision automatic positioning and visualization of defects in three-dimensional space, reduces the complexity of equipment deployment, improves inspection efficiency and accuracy, and enhances the digitalization level of bridge operation and maintenance management.
