Would this would work with good Photosynth data taken on foot from the ground? If so would things like long grass play havoc with the point cloud? I'm assuming if would try and map the grass as ground.<BR/><BR/>Look forward to seeing what you can do with thisTimhttp://www.blogger.com/profile/09139959420912333534noreply@blogger.comtag:blogger.com,1999:blog-6759912868753684019.post-17423539600348196572009-03-04T08:41:00.000-08:002009-03-04T08:41:00.000-08:00I am continuing to work on this. We've been working on figuring out the precision of the models by mapping an area already covered by LiDAR. We should have some results soon. Im also optimizing a blimp camera rig so that we can consistently shoot photos with overlap and with decent precision on the gps location of the cameras.<BR/><BR/>Ill outline a more detailed set of instructions of how to do this -- there are a couple of scripts that make the process a little easier.Carl Lipohttp://www.blogger.com/profile/05671518366138965993noreply@blogger.comtag:blogger.com,1999:blog-6759912868753684019.post-45499902361138999652009-03-03T20:15:00.000-08:002009-03-03T20:15:00.000-08:00Some great potential here! I am a grad student in the Geography Department at the University of Maryland Baltimore County. I think this type of technology may be a good addition to remote sensing and I am trying to determine how much detail within the landscape might be resolved using synths. Are you still working on this stuff?<BR/><BR/>JonathanJonathan Dhttp://www.blogger.com/profile/05634018976313753039noreply@blogger.comtag:blogger.com,1999:blog-6759912868753684019.post-51501426825199626882009-02-24T15:22:00.000-08:002009-02-24T15:22:00.000-08:00I've got three synths of aerial data with fairly decent overlap. I'd be interested in trying this technique in order to extract digital elevation data from the point clouds. One in particular has lots of 3D relief, and has been sampled fairly closely.<BR/><BR/>Would you be able to describe your workflow in more detail? I've got another package I'm using to deal with the point clouds, but the process of getting from synth to point cloud CSV file is a little opaque to me at the moment.<BR/><BR/>Thanks,<BR/><BR/>Tombenedicthttp://www.blogger.com/profile/09526265949395503306noreply@blogger.comtag:blogger.com,1999:blog-6759912868753684019.post-18976056751807585352008-12-01T20:49:00.000-08:002008-12-01T20:49:00.000-08:00I would be interested to hear how you deal with finding an optimum translation/rotation and scaling to compare with other DEM products when you get to having at look at this.<BR/>I have also made a DEM from the point cloud and have found the results impressive but it would be great to compare these with other datasets in a differing coordinate space.art79http://www.blogger.com/profile/00388734200665546502noreply@blogger.com
