I have a an unmanned aerial vehicle (UAV, also called a drone) and would like to use it to create a digital elevation model and orthomosaic over a smaller area (10 km2). My platform will be able to produce overlapping imagery with an altitude of around 120 meters (400 feet).

Several commercial products seem to provide complete solutions; eg. Pix4D and Dronemapper.

I am however primarly looking for solutions where I can have more control of the process and possibly also set up my own batching processing. Python and other open source tools are interesting.

What are my alternatives?

What type of UAV are you working with? What type of sensor? – Aaron Jul 4 '13 at 12:30

To solve the problem one needs to transform 2D images of 3D structures from different angles/perspectives into a solid model. This is known as Structure from Motion analysis.

pix4D is an overall good tool providing exceptional ease of use for inexperienced to more experienced users. A youtube video introduces the software in a good way. It is a bit in the high end with re to price.

Agisoft PhotoScan is available for Windows, OSX and Linux. The profesdional edition looks impressive, but I have not tried it.

Dronemapper is an online service where you can upload imagery and have it processed.

3Dsurvey in addition to imagery analysis also offers what looks like good point cloud editing tools.

VisualSFM is a software package which in combination with CSVS might be a way to go. A youtube movie on the www.flightriot.com webpage gives a practical example of potential endpoint products. Visual SFM seems to be a project which lacks momentum. As far as I can see there has not been any development on the software for a couple of years.

Any thoughts on the VisualSFM software? – ianbroad Aug 7 '15 at 5:23

I highly recommend Agisoft PhotoScan Pro. It costs about $3500, but they have an academic version for about $500. If you contact them they can set you up with a 30 day trial. It has a lot of options and export formats and is quite easy to pick up and get good results. They also have options for python scripting.

Another opensource option is the python photogrammetry toolbox. It takes a little work to set up but gives good results for 3D output, nothing for georegistration though.

Hope this helps!!! (even though I am a couple months late to the party)

For commercial solution take a look at http://www.3dsurvey.si/

And for opensource I would certainly try https://github.com/OpenDroneMap/OpenDroneMap

ERDAS Imagine have a UAV add in module. Combined it's more expensive than Agisoft Photoscan, but if you're already an ERDAS user it integrates really well.
