Design And Implementation Of Tunnel Face 3D_Reconstruction Based On OpenGL

It is well known that the most information of people feel is got by vision, What's more, the information is three dimensional in real world. How to better display the three dimensional information is always one of the hotspot subjects that people are concerned about. 3D reconstruction is advanced under this situation, and it is the hotspot research direction in all fields, such as computer vision, pattern recognition, computer graphic, science computer vision. Many countries make much research in this field, especially the developed ones, they research much earlier and more deeply. At present, China just begins the research of image processing and 3D reconstruction of tunnel project. Providing the vision of tunnel geology through 3D reconstruction will be a very important application in computer graphic.This project mainly develops for the tunnel project of YuanLiang hill. In order to found the data structure of 3D reconstruction system we collect a series of tunnel images and distill the information of terrane structure. The system uses the popular development tool —VC and 3D graphic development package — OpenGL which better reconstruct the 3D structure of tunnel.Main production of the thesis:1, The overall framework of the system is analysed and designed, which consists of feasibility analyses, requirement analyses, the design of function modules and the thought of the project, and so on.2, The interface of the system is designed for better associating all function modules. So when using the system, the users will feel friendly and easily work.3, At Iast, the design and implementation of 3D reconstruction of tunnel face is instrodueced, including construction of data structure, triangle algorithm of AFT, implementation processing and effect display. Furthermore, discussion and improvement of AFT is advanced for making it better apply to reconstruction of tunnel face in the system.
