Fire operation violation detection method and device

The invention provides a fire operation violation detection method and device. The method comprises the following steps: acquiring a real-time operation image of a fire scene; in a feature extraction network of a target detection model, feature extraction is carried out on a direction feature map carrying a width attention weight and a height attention weight, and a target feature map of the real-time operation image is obtained; in a target recognition network of the target detection model, marking a target object related to the fire operation in the real-time operation image by recognizing the target feature map to obtain a marked operation image marked with a target detection result; and based on the marked target detection result in the marked operation image, in combination with a preset fire operation rule, determining whether a violation operation behavior exists in the fire scene. Therefore, whether illegal operation behaviors exist in the fire scene or not can be detected in real time, so that the re
