Abstract: Aiming at the problems of scattered isolation, picture limitation, low utilization rate and poor correlation of traditional video monitoring in coal mine, this paper studies the mapping fusion technology of monitoring video and three-dimensional model to make the original fragmented real-time monitoring video in a whole scene 360° panoramic stereo monitoring and realize the organic combination of virtual model and real-time monitoring. 360° panoramic stereo monitoring helps users quickly survey the whole situation of the mine, which improves the safety assurance ability and monitoring traceability efficiency.
