Do you know the license you will use to release your software? we are trying OpenWebGlobe (http://swiss3d.openwebglobe.org/).<br />thanksAlessandro Bezzihttps://www.blogger.com/profile/05522144031611111783noreply@blogger.comtag:blogger.com,1999:blog-4458817758216594734.post-67502487069283764682012-10-18T23:53:45.878+02:002012-10-18T23:53:45.878+02:00FYI i've made a rudimentary (for now, but i do...FYI i've made a rudimentary (for now, but i don't have many time to continue to work on it) WEBGL based point cloud viewer vizu.herokuapp.com. It's build upon the play framework (server side) and three.js (client side).

Then pmvs do the match. <br />Maybe if you send me your photo set i can try to make do something with MicMac.

More images = more slow". if i remember well, with 100 images the time of calculation of PPT was only 48 hours.<br />i will make a new test elaborating the inner floor of the same building (other 120 photos) and control again the time. Maybe there was a problem with the first photoset.Alessandro Bezzihttps://www.blogger.com/profile/05522144031611111783noreply@blogger.comtag:blogger.com,1999:blog-4458817758216594734.post-40706491036247936772012-10-18T19:47:20.762+02:002012-10-18T19:47:20.762+02:00Hi,

One of the thing I like about SfM and IBM is the few interaction the software need, so while the computer is processing the data, you can work on other things. But this is just my opinion :)Luca Bezzihttps://www.blogger.com/profile/01679160024950021679noreply@blogger.comtag:blogger.com,1999:blog-4458817758216594734.post-81883988176413504442012-10-18T19:13:12.071+02:002012-10-18T19:13:12.071+02:00Hi Romain,

We alredy tested MicMac (http://arc-team-open-research.blogspot.it/2012/03/example-test-of-micmac.html), but just with the default data. We were waiting for a motivation to test further this software and your comment is a good reason to try MicMac with quasi planar objects and see the difference.Luca Bezzihttps://www.blogger.com/profile/01679160024950021679noreply@blogger.comtag:blogger.com,1999:blog-4458817758216594734.post-44659819859022652202012-10-18T13:40:34.344+02:002012-10-18T13:40:34.344+02:00Amazing results!

But sometimes is better to create a single model using point cloud results from different PPT processes. You can waste lots of time processing a large image set with RunBundler and finally discover that RunCMVS can only use a small number of those images (i.e. blurry photos, not enough common features). I'm not pretty sure, but apparently when feature matching phase is running, things also start to get incrementally slow. More images = more slow.<br /><br />rgaidao Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4458817758216594734.post-29698168189418552712012-10-18T09:38:11.001+02:002012-10-18T09:38:11.001+02:00Hello,

For exemple i think 8go is not enough to manage 100 pictures at full resolution, so you may have swapped (it can explain the 60 hours of calculation). For quasi planar object like this, (it's basically 4 wall, so 4 quasi planar objects) I should advice you to Use MicMac, which is based on depth map calculation, from the French Geographical Institut http://www.micmac.ign.fr/.
