There are a large heap of patents in this area of technology; you had better ruminate before you encourage others to invade that IP.

From a more practical point of view there are two further issues: - there needs to be some compensation for potential differences in exposure between shots on adjacent cameras (a KISS approach might have 3 parallel cameras for each angle, one with auto exposure, one higher, one lower, with post-processing to determine which of the shots to use from each camera based on exif tags, histogram analysis etc...) - capture in suboptimal conditions should be avoided - this included the obvious such as avoiding precipitation, but also bright sunlight. Fortunately northern Europe is blessed with clouds providing many hours of lovely diffuse light ideal for photography.

Panorama tools for stichting/manipulating images seem to be a solved problem (where 'solved' means it is either solved, or there is a large community actively working to solve the open issues)... For example, Panotools has five Google Summer of Code students working on things... http://panotools.sourceforge.net/ We'll need to create some glue to automate things, but the heavy lifting code exists... so what are the open questions? -setting up multliple cameras -exposure control for the different cameras -capturing location - 'obviously' GPS, but I suspect we'd like AGPS resolution, and probably a compass independent of the GPS track (ie. built in compass seems okay, but counting on the track log requires you to be moving , and isn't all that accurate. :-/ -Processing images-panotools seems to have what we need. -storage-initially a random server will work. -API to access imagery -> seems like 'a few scripts' -viewer - panorama viewers exist already, but we would like some cool map based interface next to the panoramas. These don't seem like hard questions, but I don't have off the cuff answers for all of them. Any questions I'm missing? Any answers?

In experimenting with Autostitch, the results are pretty amazing how well it can make the pano seamless. The web site for the software shows a typical example. http://cs.ubc.ca/~mbrown/autostitch/autostitch.html ------------------------------ _______________________________________________ Geowanking mailing list [email protected] http://lists.burri.to/mailman/listinfo/geowanking End of Geowanking Digest, Vol 43, Issue 14 ****************************************** _______________________________________________ Geowanking mailing list [email protected] http://lists.burri.to/mailman/listinfo/geowanking
