Fire environment detection method and system based on image data

The invention relates to the technical field of fire environment detection, in particular to a fire environment detection method and system based on image data, in an initialization stage, the system generates a data stream identifier, then a fire detection model is constructed, the performance and efficiency of the model are improved through an optimized FC2f module and a SharedDeect lightweight detection head, and finally, in a real-time detection stage, a real-time detection result is obtained. A video stream collected by the camera is transmitted to the environment data processing module, the environment data processing module preliminarily processes the video stream, the fire environment detection module confirms the source of the video stream and sends the video stream to the fire detection model for analysis, detection result output and fire risk grade division, and the decision support module tracks a fire occurrence area. And an emergency management suggestion is generated. Through the lightweight YO
