Display System Of Virtual Sculpture In Real Scenery Based On Augmented Reality Technology

Augmented Reality (AR), arising from the early of 1990s, is a new technology and research hotspot in recent years. It is an important branch of Virtual Reality (VR) technology with the features of combining virtual and real objects, real time interactions and 3-D registration. Different from Virtual Reality system, Augmented Reality technology is only in the experimental stage. Although the research of Indoor Augmented Reality systems has got a great evolution, there is not a mature application system in Outdoor environment up to now. From the above conditions, an Outdoor Augmented Reality system named display system of virtual sculpture in real scenery is developed, for exploring the realization of Outdoor applications with AR technology. By evaluating the result blended video, the designer can estimate and optimize the layout of virtual scene intuitively, and eliminate the inaccuracy during the planning process through this system.The topic has explored the technical realization of scene display systems of virtual sculpture based on Outdoor Augmented Reality and application models in the field of Designing and Planning. According to the fundamental characteristics of Augmented Reality and the operation of the system theory, this thesis has analyzed the system functions and performance requirements, discussed the framework of the system, which included the hardware and the software configuration theory, expounded the related algorithms and the operation processes of the system, achieved the GUI design and a prototype, and finally made the experiment of the prototype and obtained the preliminary results. During the realization of the prototype, it reads the video kinescope of real scenes into the system firstly, identifies the chromatic markers in the video images to obtain the information of them, calibrates the camera parameter based on the Markers' information, registers the virtual scenes and real world to obtain the relationship matrix of them, and finally realizes the blending of the virtual scenes and the real scenes. During the realization of the prototype, for the Outdoor environment, marker of points in 3D registration is adopted, and the correctness of this algorithm is confirmed by realizing it in system. This thesis has explored the related issues of scene display systems of virtual sculpture based Augmented Reality, and preliminarily realized the prototype system, which provides an initial experiment platform and strong reference for the deeper and wider research in future.
