Abstract

3D video mosaics created by 3D image mosaicking, our previous research, are for 3D visualization of the roadside standing building scene captured by a side-looking video camera as a continuous set of vertical-textured planar faces. These vertical faces were concatenated to create an approximate model on which the images could be back-projected as textures. We proposed a retrieval technique of selecting vertical-textured planar faces from archived 3D image mosaics to fast represent a 3D world, where this selection is based on proximity to the user location in the virtual world. The chosen vertical-textured planar faces are recomposed as a continuous set formed stream and are then rendered in 3D virtual space.
