Walking into Images: Virtual Plane Mosaics for Plenoptic Modeling

摘要

An effective method of depth image based rendering is proposed by applying texture mapping onto virtual but pre-defined multiple planes in the scene, called virtual planes. The method allows the viewpoint either static or moving around, including crossing the plane of the source images. By this approach, the relief textures from depth images are mapped onto the virtual planes, and through the pre-warping process, the virtual planes are converted into standard polygonal textures. After the virtual plane mosaics, the resultant image that supports 3D objects and immersive scenes can be generated by polygonal texture mapping. In addition, both hardware and software implementation of the method can increase the power of conventional texture mapping in image based rendering. In particular, the scope of the viewpoint could be extended into the inner space of depth images, and as a result, a novel solution is provided for constructing real-time walkthrough systems as well as for panoramic modeling from an arbitrary viewpoint in the depth image space.
