Study On 3D Visual Safety Supervision System Of Smart Mine Based On Cesium

Mining is the basic industry of the national economy,and mineral resources are an indispensable material basis for human survival,economic construction and social development.Intelligent mining is the strategic direction and development goal of the transformation and upgrading of the mineral industry.It is the core technical support to ensure national energy security and realize the high-quality development of the mineral industry.With the development of cloud computing,big data,artificial intelligence,Internet of things,virtual reality,three-dimensional visualization and other new generation information technologies and their application in the mineral industry,intellectualization has become a new breakthrough in the field of scientific and technological revolution after industrialization,automation and informatization.In this thesis,the combination of three-dimensional visualization and video monitoring is applied to mine production,which not only meets the needs of daily video monitoring,but also more intuitively reflects the location information of monitoring,and greatly improves the efficiency of monitoring.Based on cesium,the construction of smart mine is realized by combining 3D visualization and video monitoring,which can be applied to mine safety scheduling and play a certain role in mine safety production.The main achievements of this thesis include:(1)The terrain and buildings in the mining area are modeled in three dimensions.The photo data of the mining area are collected by UAV tilt photogrammetry technology,and the threedimensional modeling is carried out by context capture software.The buildings in the mining area are finely modeled by 3DMAX.Different formats of model data are loaded through cesium,and different types of data need to be converted.(2)Based on the data visualization method of cesium,this thesis focuses on the loading and rendering of image service,terrain service and 3D model data,and realizes the loading and visualization of massive data.(3)Research on the three-dimensional visual safety supervision system of smart mine based on cesium.According to the B/S architecture,the server is built,and functional modules such as monitoring screen,real-time early warning,personnel supervision,geographic fence,video monitoring and hidden danger account are developed to realize the visualization function of the mine,achieve the rapid loading of data and the effect of mine safety supervision.There are 34 figures,12 tables and 70 references in this thesis.
