Abstract 12 A compact visual representation, called the 3D layered, adaptive-resolution, and multi-13 perspective panorama (LAMP), is proposed for representing large-scale 3D scenes with large 14 variations of depths and obvious occlusions. Two kinds of 3D LAMP representations are 15 proposed: the relief-like LAMP and the image-based LAMP. Both types of LAMPs con-16 cisely represent almost all the information from a long image sequence. Methods to con-17 struct LAMP representations from video sequences with dominant translation are 18 provided. The relief-like LAMP is basically a single extended multi-perspective panoramic 19 view image. Each pixel has a pair of texture and depth values, but each pixel may also have 20 multiple pairs of texture-depth values to represent occlusion in layers, in addition to adap-21 tive resolution changing with depth. The image-based LAMP, on the other hand, consists of 22 a set of multi-perspective layers, each of which has a pair of 2D texture and depth maps, 23 but with adaptive time-sampling scales depending on depths of scene points. Several exam-24 ples of 3D LAMP construction for real image sequences are given. The 3D LAMP is a con-25 cise and powerful representation for image-based rendering. 2
