Analysis of Panoramic Technology of Coal Mine Roadway Based on 3DGIS

The panoramic technology of coal mine roadway based on 3DGIS is combined the existing panoramic technology with 3DGIS technology in the special environment of coal mine roadway. Users can browse the distribution, state and structure of coal mine roadway by computer and other related equipment, it has a wide range of applications in safety training, emergency rescue and other aspects. The panoramic image is more dynamic and interactive compared with ordinary 3d images. Through the analysis of the panoramic technology, the analysis of the spherical projection and the introduction of the SIFT feature matching algorithm, we have a preliminary understanding of the panoramic technology of the coal mine roadway based on 3DGIS.
