Build A Three-dimensional Virtual Scenes Based On Two-dimensional Architectural Graphics Design And Realization

Since the rapid speed development of Computer Science, Communication Technology and the other related technologies, at the same time, Information Visualization Technology becomes the new field of Research and application, Currently, the Simulation Technology based on Virtual Reality(VR) is being increasingly and become as the current research focus of academic computer at domestic and foreign, The VR technology will constructs a lifelike environment that is very similar with the real environment by computer, by the Man-Machine Interface between user and the virtual environment, it makes the user immersing virtual environment. Conventionally, the modeling technique is manually, it is low efficiency and waste work force. But the new techniques of 3D reconstruction are lack a systemic solution. This paper is to find out a solution to solve this problem.In this paper, it introduces a whole systemic solution to implement the 3D reconstruction from 2D frame sequences. And develop a tool called 3D Re-Construction (3DRC). The solution contains four modules: camera parameter calibration module, 3D computing module, 3D reconstruction module and photo processing module. First, the function of camera parameter calibration module is used to get the inner parameter of the camera from photos automatically. Second, the function of 3D computing module is used to extract the 2D information of the feature points from its photos and compute the 3D information of them, then save the 3D information in the file. Third, the 3D reconstruction module is used to read the 3D information and reconstruct the 3D model of the object in computer and save the model files at the same time. At last, the function of photo processing module is used to translate, map and integrate the 3D models, it also transform the file format distinguished by scene system and finish the design of other material, construct the virtual scene.The systemic solution introduces in this paper implement 3D reconstruction to a highly automatic process, and makes the ordinary users to reconstruct the 3D models easily. Also, it offers a research method for the relative research fields.
