River Blocking Judgment Based on Color Constancy Color Similarity Measure under Complex Disasters

This paper analyzes the map formed by aerial photography of drones, and uses the color constancy color similarity measure CCCI and binary image similarity measure to judge whether the river is blocked and the degree of blockage, instead of the previous artificial judgment on the barrier lake. The results show that the CCCI water body extraction method is less affected by the mountain shadow and thin cloud, which can completely eliminate the “Noise water body” phenomenon caused by the pixel-based CCCI water body extraction method.
