Route panorama
Encyclopedia
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. 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 moving panorama
for access of geospatial locations, navigation, georeferencing, etc.
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 camcorder
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 Photomontage
. Under the same circumstance, a dynamic slit selected in the video frame can generate a route panorama with less shape distortion.

Moving panorama
The moving panorama was a relative, more in concept than design, to panoramic painting, but proved to be more durable than its fixed and immense cousin. The word “panorama” is derived from the Greek words “to see” and “all.” Robert Barker invented the first panorama to describe his impressive...

Photomontage
Photomontage is the process and result of making a composite photograph by cutting and joining a number of other photographs. The composite picture was sometimes photographed so that the final image is converted back into a seamless photographic print. A similar method, although one that does not...
