As an important branch of visual reality technology, augmented reality has been applied to vast fields like commerce and education. This paper verifies the feasibility of applying augmented reality technology to the planning of residential district. A visual district planning system is designed and realized on the basis of augmented reality. It fully reflects the advantages of augmented reality technology in the application to district planning by meeting the requirements of district planning for visual-real interaction and man-machine interaction. This paper further describes visual-real registration technique based on computer vision and adopted by the system. Moreover, the results of system operation are given.
Geographic visualization is a hot point in recent years. Many new methods for spatial information visualization have been developing. In this paper, we introduce a new Augmented Reality based geographic visualization system which has the properties of virtual- real combination and human-computer interaction. Registration is the key technique to realize the seamless combination of virtual and real objects. We mainly discuss the pattern and nature feature based registration algorithm used in our system.
This paper describes an Urban-Plan System based on augmented reality with tangible and interactive user interface. Virtual models, graphics generated by computer and physical materials have been used in whole urban-planning process. Participants can carry out their assignment collaboratively in direct and interactive manner and the final results can be browsed and modified in real-time. Augmented Reality enables users to achieve Urban-Plan more effectively and easily. One key object of our system is to enable users manipulate virtual models as they can do in real world. To achieve this, we must calculate the pose and position of camera relative to real world exactly. This paper uses computer vision technology and known marker to solve the above problem.
