Easy tour

Abstract

In this paper, we describe a new image-based virtual tour system: Easy Tour. The system is built on panorama and TIP techniques. With this system, the user can create panoramas and edit hot areas. The hot area in the scene map corresponds to a panorama sight and the hot areas in each panorama correspond to TIP sub-sights. Through modeling the sight navigation into global model and local model, the user can virtually tour the scenes. Because of the draw-backs of panorama and TIP techniques, some improvements are presented in this paper. A new dynamic programming algorithm is presented to remove ghosting in the mosaiced image. To interactively smooth transition between TIP scene and panorama scene, a modified modeling process is presented to remove holes in the modeled TIP sub-sight and a straight line interpolation method is used to realize eye transition between global model and local model.
