A community natural disaster damage degree assessment method and related device

Abstract

The application discloses a community natural disaster damage degree evaluation method and related device. The method comprises the following steps: obtaining a community disaster image; extracting an image feature map in the community disaster image through a backbone feature extraction network, performing tiling processing on the extracted image feature map, and obtaining a feature sequence; performing adaptive region aggregation on the feature sequence by using a learnable region query vector, generating a plurality of local region features and corresponding region center positions; constructing inter-region semantic relationship and spatial relationship based on the local region features and the region center positions, and fusing to form a comprehensive region relationship matrix, performing relationship propagation update on the local region features, and obtaining the local region features after relationship enhancement; and performing importance weighted aggregation on the local region features after relationship enhancement, and generating a community overall damage representation. The application can improve the accuracy and stability of community disaster damage evaluation.
