Research And Application Of 3D Real Scene Modeling And Visualization Technology Based On Multi-Source Data Fusion

The battlefield environment is the key factor affecting the direction of the war.The terrain is the main component of the battlefield environment.With the changes in military technology;,precision strikes,and the use of precision dagger weapons,the limitations of traditional two-dimensional maps have been unable to meet the needs of military training and military command.For the current 3D battlefield shape,the requirements for rapid terrain model construction,terrain model refinement,and mass data visualization are becoming more and more high.Therefore,this paper has carried out in-depth research to construct a real three-dimensional battlefield geographic environment and visualization.In this paper,the oblique photography technology and Cesium visualization library are used to establish the real three-dimensional terrain and the construction of the visualization platform.The Weiyang Campus of Xi'an University of Technology is used as a typical application example for urban combat visualization development.Firstly,this paper introduces the theory of 3D real-world modeling and visualization;discusses the advantages of visual development on the Web;and puts forward the problems and solutions to the 3D battlefield construction.Secondly,this paper has developed a multi-source data acquisition scheme for battlefield environment and a modeling process based on Smart3D multi-source data fusion.The 3D battlefield shape data was produced and the model quality analysis was carried out,including the texture accuracy,geometric precision and geographic coordinate precision of the model.Ensure that the generated interventions on the ground personnel.Finally,based on the first three chapters,this paper adopts the B\S three-tier architecture to construct the battlefield environment visualization platform through Cesium,HTLM,JavaScript and other languages,and realizes the three-dimensional battlefield environment construction of urbanization operations.At the same time,this paper completes the functions of model singularization and model driving based on Cesium.This topic is of great significance to the construction and visualization of 3D battlefield environment.The battlefield environment construction method proposed in this paper can be applied to the construction of various battlefield environments,including the construction of combat terrain environment in mountainous hills and urban anti-terrorism operations.Through the loading of the visualization platform,you can intuitively and truly understand the battlefield environment.Model-driven completion of various demonstration effects in the battlefield.
