In my previous post on Getting Bundler and friends running, I suggested how to modify an existing script to get Bundler and other structure from motion parts/pieces up and running. Here’s my follow up.
Download (or clone) this repo:
Navigate into the cloned or unzipped directory (on the command line), run
Go have a cup of coffee. Come back. Run
Congratulations. You have an Ubuntu machine capable of all sorts of StructureFromMotion / OpenDroneMap goodness.
Next: A tutorial on how to use the tools you just compiled… .

Anyone who has jumped down the rabbit hole of computer vision has run into dependency h*ll getting software to run. I jumped down that hole again today with great success that I don’t want to forget (these directions are for Ubuntu, fyi).
First, clone BundlerTools:
This will download and compile (almost) everything for you, which is a wonderful thing. The one exception is graclus. This doesn’t have a direct download access anymore– you have to register, and then you will receive and e-mail with the download. So, to get the BundlerTools to work, you will need to post this someplace web accessible. Then open and modify install.sh (https://github.com/qwesda/BundlerTools/blob/master/install.sh) and change the following line (128)
to match your new download location.
Now change install.sh to executable:
chmod 700 install.sh

I have been contemplating all sorts of varied uses of Structure from Motion techniques. One of those outputs, in addition to using sUAVs (drones) is just to orthorectify and generate 3D meshes from ordinary photos. This has really great potential for linear assets like streams and rivers, trails and roads. We’ll have to
being to contemplate how we’ll use (and summarize!) the incredible amount of data and information that will suddenly be available to us, e.g. this subset of an orthophoto of a multi-purpose trail:
