Route panorama is a continuous 2D image that includes all the scenes visible from a route, as it first appeared in Zheng and Tsuji's work of panoramic views in 1990.
Overview
Different from a local
panorama at a static viewpoint, a digital route panorama is constructed from partial views at consecutive viewpoints along a path. A general approach to obtain such a complete route panorama is to use a line camera or slit camera mounted on a vehicle moving along the path smoothly. The camera scans temporal scenes in the side direction of the path and connect them to the spatial image. This is realized by a program that processes temporal image data or video data in a computer. The route panorama can extend to a long distance for indexing scenes and navigation on the Internet. The long image can further be transmitted to and be scrolled on computer screens or handheld devices as

Mathematically, the route panorama employs a parallel-and-perspective projection that is a continuous and extreme case of multi-perspective view to pixel lines. It may have the aspect ratio of an object different from what a normal
perspective projection generates. In addition, a video

is used to produce the route panorama by taking only one pixel line in the video frame at a time with the
auto-exposure function of the camcorder and shaking removal function using the inter-frame matching.
If the depth of scenes from the path has a dominant layer, a route panorama can also be created on that layer by
stitching discrete photos consecutively taken along the path using

. Under the same circumstance, a dynamic slit selected in the video frame can generate a route panorama with less shape distortion.
