Method of panorama-based navigation for 3D room

A novel method of an augment reality is presented. The method is different from the traditional ones, which solves the two key problems in augment reality: a camera calibration and a dynamic model matching. A rough estimation of the camera's orientation is primarily got by comparing with the panorama, the correspondence between the real image and the two-dimensional image model is solved subsequently, then the navigation can be achieved in this environment. Three-Dimensional model need not to be built in this method, as well as other assistant instruments or calibrated objects, which they are required in traditional methods. This method is simple with good accuracy. Its application in navigation for three-dimensional room is also provided. It is assumed that the pitching of the observer is small, since it satisfies most applications. This method is used in some practical systems.
