Study On Virtual Scene Visualization Based On OSG And The Relationship With Imaging System

Virtual reality visualization technology is an emerging science and technology. It has been widely used in military, aerospace, national defense and some other fields, and it also earns more and more attention. And the virtual imaging technique is one of the important means of photogrammetry. It has greatly promoted the development of simulation visualization technology, and has a promising application prospect.This paper firstly establishes a3D model in virtual scene used the Multigen Creator, a3D modeling software, and also establishes a visual virtual scene through the3D rendering engine OSG technology in the VS2010platform; then analyzes the relationship of the visual imaging mechanism and OSG imaging mechanism, and derives the transformation formula between them; finally studies the relationship between visual virtual scene and the imaging system of OSG, sets up a virtual imaging simulation platform, obtains the2D images from3D scene.The analyses of imaging and the experimental results of imaging in this paper prove that the accuracy of the images generated by imaging simulation platform developed by OSG technology meets the demand of visual imaging system, and this method can improve the visual effect and save the costs of development.
