Projector-based VR
In projector-based virtual reality, modeling of the real environment plays a vital role in various virtual reality applications, such as robot navigation, construction modeling and airplane simulation. Image based virtual reality system is gaining popularity in computer graphics as well as computer vision communities. The reason is that is it provides more realism by using photo realistic images and the modeling procedure is rather simple. In generating realistic models, it is essential to accurately register acquired 3D data. Usually, camera is used for modeling small objects at a short distance.
