Where to start?


As I posted on my previous topic, I am interested on coding the needed parts to add thermal processing to ODM with all its specific issues.

I have some ideas on how to proceed but I am not familiar with ODM code repository structure. I cannot find code where it performs the “stitching” procedure, for example. Where is all that code?

It is quite difficult to become familiar with this repo without a “high-level” developers guide.

Any help with this?

A good topic to start: Where can I find background information on the concepts of ODM? - #2 by pierotofy

Also https://odmbook.com has a chapter on the reconstruction pipeline, which might help understand the various pieces from a user perspective (disclaimer: I wrote the book).

There’s no stitching (technically speaking), ODM performs true orthophoto generation, which is the result of multiple stages (points → mesh → texturing → final orthophoto). See https://support.pix4d.com/hc/en-us/articles/202558869-Photo-stitching-vs-orthomosaic-generation

Examine the various stages of the pipeline, one at a time (skipping split-merge, which is one more level of complexity). ODM/stages at master · OpenDroneMap/ODM · GitHub

Each stage might invoke external modules for performing its task (points → opensfm, meshing → poisson recon, texturing → mvs-texturing, etc.). The code for those are downloaded from ODM/SuperBuild at master · OpenDroneMap/ODM · GitHub at build time.

Great stuff here!

@pierotofy Is there any other ways to try ODM other than docker. Because i get "No space left on device " error while using docker.Can we build ODM from source. If so can you help me with how ?
