(of course also in computer vision, medical imageing, etc.) i had a quick look @ http://lensfun.berlios.de/manual/elem_calibration.html and also read in the ML archive the high-quality disscussion you guys had. (lot's of useful info there!) e.g. http://lists.freedesktop.org/archives/create/2007-August/thread.html http://lists.freedesktop.org/archives/create/2007-September/thread.html#932 > Since this list is not the best place to flood about it, agreed! > I propose all further discussions to be moved to the dedicated berlios > forum and bug/patchtracker. mmh, maybe an new mailing list, dedicated to photogammetry? basically we share the very same problem, but our practical realisations of a camera/sensor are quite broad. e.g. a DSLR camera has a tiny CCD-sensor on it's back-plane, while a professional aerial camera has a back-plane of 350mmx350mm, etc.. e.g. on the geomatics/remote-sensing side OSSIM ( http://www.ossim.org ), also already has support/code for lens correction for modern aerial cameras (but basically that's the same. lens-correction is useful for all cameras/sensors with lenses :) GRASS GIS ( http://grass.itc.it/ ) on the other hand does not even have lens-correction support at all it appears. ( yesterday night i was wading throu the code, i couldn't spot any. feel free to correct me. http://freegis.org/cgi-bin/viewcvs.cgi/grass6/imagery/i.ortho.photo/ ) > My plans is to start adding support for it into UFRaw. great. so with ufraw-batch it will be possible pre-process aerial photos (which were shot with a DSLR camera) to rectilinear, and when further process them in GRASS. looks good. > I hope this real-world usage will show the weak points of the library, > especially > because in UFRaw it will be a very untypical usage (applied on a bayer > image). cheers, s. _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
