Abstract: The traditional mine video monitoring has the problems of large amount of video data,poor correlation between video images,and lack of direct linkage with the three-dimensional spatial location information. It is difficult for regulators to effectively reproduce the scene and location in the face of multiple fragmented monitoring video images,which makes it impossible to solve relevant problems in time when emergencies occur,and seriously affects the timely and effective development of mine emergency rescue work. In view of the above problems,a mine video monitoring method based on three-dimensional video fusion is proposed. Using three-dimensional video fusion technology,the real-time monitoring video is used as a texture to construct a geometry,and the feature points are selected and matched to fuse with the mine three-dimensional model. On this basis,in order to make the three-dimensional video texture fusion effect better,the Laplacian grid deformation algorithm is adopted to correct the distortion of the video geometry texture. The experimental results show that the three-dimensional video fusion has a strong visual perception effect. The video and video are interrelated,and the fragmented video is integrated. The fusion of video and three-dimensional model solves the problem of non-linkage between three-dimensional space data and video,makes up for the defects of traditional video monitoring technology,and enriches the means of mine monitoring.
