The application provides a kind of based on double knowledge graph's pneumoconiosis X-ray chest radiograph classification method, device, equipment and storage medium, it is related to medical image processing technical field.The method comprises: after lung segmentation is carried out to chest radiograph, utilize the frozen CLIP visual encoder and its embedded multilevel residual adapter output multistage enhanced visual features to strengthen subtle lesion expression;Based on medical classification standard, construct text and visual double knowledge subgraph, carry out graph convolution interaction and fusion to original text features and subgraph, obtain optimized text features;Visual and text features are mapped to unified semantic space, the similarity of hierarchical alignment is calculated, and the classification result is obtained by attention mechanism fusion.The present application introduces medical priori through knowledge graph, combined with multilevel visual enhancement, can significantly improve the recognition ability of pneumoconiosis lesion and cross-modal semantic alignment accuracy, realize high-accuracy automatic classification.
