AI Technical Summary
Existing digital twin modeling methods for water conservancy are difficult to take into account areas with significant local curvature changes when dealing with complex terrain. This results in deviations between the constructed spatial reference surface and the physical entity at slope turning points or structural connection points, affecting the geometric shape and structural response expression of the digital twin.
By acquiring multi-source heterogeneous data, a spatial reference surface is constructed after preprocessing. Geometric primitive regions are extracted from the surface for subdivision. The spatial reference surface is iteratively optimized using morphological correction coefficients. By combining wavelet transform and weighted fusion of evidence primitives, the real-time updating of the water conservancy digital twin is achieved.
It effectively improves the geometric shape fitting effect and equipment status diagnosis reliability of water conservancy digital twins under complex terrain conditions, ensures the overall smoothness and the fit of local geometry, and improves the reliability of fusion confidence allocation results.
