Then just divide the 35mm equivalent focal length by the crop factor, 26 / 5.8643, and get a resulting actual focal length of roughly 4.4336mm. Your phone uses a 1/2.4" type sensor, which according to the detailed version of the openMVG sensor database is roughly 5.9x4.43mm, with a diagonal of about 7.378mm. A bit more research, though, and I now think you might be able to do it, or at least get close.įirst calculate the crop factor of your sensor, basically the ratio between your camera's sensor size and the sensor size of 35mm film that's 36x24mm, so the diagonal is roughly 43.2666mm. I thought about that before I replied to you, but wasn't sure if it was possible. I have hope that sooner or later I'll be able to put together a guide or at least sample Destination using Regard3D that I can share, but in the meantime I thought at least a few people would find this software as interesting as I did. Find the width (not diagonal) and add your camera to the database following the format you see for the other entries. Once that's in place, the program should launch without complaining, and you can start with the tutorial. You'll want to put sensor_database.csv in the main Regard3D directory, alongside the main executable. There's a Github repo for the code, and build instructions are on the project's website easily enough. If you're running Linux instead, I'm sorry to say you'll have to build from source.
FREE PHOTOGRAMMETRY SOFTWARE FOR MAC DOWNLOAD
To use Regard, Windows and Mac users can download binaries from the project's site. Nonetheless, as is customary on the internet, I'll remind everyone that I am not a lawyer, so don't assume I know what I'm talking about regarding software patent law.
OpenMVG, one of the base libraries Regard depends on, also uses it by default, but the developer stripped it out and implemented alternative solutions.
FREE PHOTOGRAMMETRY SOFTWARE FOR MAC FREE
Regard is free for commercial work just as much as non-commercial, and patent free (to the best of the author's knowledge) since he's gone out of his way to avoid David Lowe's SIFT feature extraction algorithm, which many such programs use. I stumbled over it a few days back, and although I don't have any finished workshop content to show off just yet, I'm optimistic based on what I've seen from the software so far.
Regard3D [is a free, open source photogrammetry tool available for Windows, OS X and Linux. I've hemmed and hawed for a few days about where exactly to post this, but finally decided to just make a dedicated thread and get it over with.
