A method for mine fire identification and fire source location based on binocular vision |
| abstract |
The invention discloses a fire identification and fire source localization method based on binocular vision. The main steps include: using a stereo matching method to visually register binocular cameras installed in key monitoring areas in the mine, and fitting the estimated distance of the target to match The functional relationship of the measured distance; the video image is identified by the deep learning model; when a fire is identified, the estimated distance between the fire source and the camera is calculated by binocular vision, and the functional relationship between the estimated distance and the measured distance is brought into, Real-time location of the fire source. The fire identification and fire source positioning method of the present invention has the advantages of wide monitoring range, good real-time fire monitoring, high accuracy, and accurate positioning. At the same time, it overcomes the problems of false alarms and omissions in the mine fire identification by the existing multi-source sensor fire monitoring devices. When the flame characteristics of the fire field are unstable, the flame identification method based on image features directly leads to the reduction of the fire source identification rate. |
