Re: [Qgis-user] OpenSource software for Drones
FYI, I am just in the process of completing an introductory tutorial on MicMac including orthorectified imaging. At the moment it is all in French, I will translate it to English as soon as this initial draft is proofread by some friends (ongoing work so the included images have not yet been shrunk to a manageable size ... huge PDF document at the moment). In the mean time you can have a look at the pictures to see what topic will be addressed: http://jmfriedt.free.fr/lm_sfm.pdf The topic of UAV is addressed with some images acquired from a toy and processed using MicMac (p.13 of my document). MicMac is absolutely fascinating and well worth the time: I have only been involved for the last couple of months but can't stop acquiring pictures for SfM everywhere I go now. Any French speaking reader on this list who might have some comment on the document is welcome to do so.

My goal was to be able to reliably provide ortho-rectified high resolution imagery. Here are some of things I've learned: 1. It is possible to buy some off-the-shelf systems (e.g. www.aeryon.com/products/avs/aeryon-scout.html ) but they can cost $20K to $60k and are not open (on the other hand, they are very reliable). 3DR (the commercial store for DiyDrones) has cost-effective, open systems. They just released their Iris/Pixhawk systems. 2. The DIY Drones ecosystem is mostly populated with people who just want to build, fly, and experiment with their own UAV platforms (frame, powertrain and flight controller), but there a few people interested in acquiring and processing UAV imagery as well. Personally, I look at a UAV as [just] a camera positioning system ;) 3. Most of the software development effort in UAV image processing comes from the computer vision space (e.g OpenCV). Google structure from motion for more info on that type of processing chain. I'm unsure if that method pays enough attention to rigorous image geometry to produce accurate ortho-rectified imagery. Maybe; at any rate I want DEMs and geotiffs as an end result (I think) and that chain tends to produce non-georeferenced 3D models. And if you've got a few hours to burn reading current research, google UAV SLAM... 5. MicMac ( http://logiciels.ign.fr/?-Micmac,3- ) seems to use photogrammetric principles, is set up to use UAV imagery, and is Open Source, but as I mentioned before the learning curve is steep. Their user forum ( http://forum-micmac.forumprod.com/ ) has links to the user doc (280 page PDF!) and some sample data to work thru the examples in the user doc. Another possibility is OSSIM/OTB, and while their algorithms are excellent, I don't think the software is set up to deal with hundreds of images (bundle adjustment, etc), and it doesn't produce DEMs (yet). 6. Lots of R D to be done yet. For example, using RTK/Post-processing to calculate accurate camera centers (so no ground control points necessary). Some models of the cheap UBLOX GPS receivers can generate pseudo-range info, so RTKLib is a possibility. Good Luck!

Re: [Qgis-user] OpenSource software for Drones
Interestingly enough, the main ground station software for the 3DRobotics/DIYDrones stuff is based on Qt like QGIS is. http://planner2.ardupilot.com/ and https://github.com/diydrones/apm_planner I wonder if there are opportunities for direct integration. CC'ng a friend of mine at 3DR that works on the android based ground station as he may know more or be able to point you at other resources. I own a 3DR MultiRotor, but as Brent said, the learning curve is very steep and long. The craft from DJI are supposedly a little more easy to use, but are not open source in any way as far as I know.

Lene, Similar to Alex's answer, a good source of information is http://diydrones.com/, with links to Arducopter (APM) for actually flying the drone, and Mission Planner for managing and configuring APM. I've been trying to find a good Open Source stack for processing drone-acquired imagery; so far I've settled in MicMac ( http://logiciels.ign.fr/?-Micmac,3-) from IGN (France), but the learning curve is steep and long Best Regards, Brent Fraser On 6/18/2014 3:01 PM, Lene Fischer wrote: Hi, We are looking into possibilities to start flying with drones.
