Read all the docs but not sure I know all the programs run during an ODM project. All I have found so far is: ODM, Opensfm, QGIS, CloudCompare, and meshlab. Are there others?
I think it is actually grass/gdal/libLAS for that part of the pipeline, not QGIS.
Correct. And cloudcompare isn’t directly used, although I personally use it all the time to view point clouds from OpenDroneMap.
Um, which is correct, smathermather-cm? QGIS or grass/gdallibLAS?
Grass. But it’s used only for split-merge.
Are the algorithms used documented at the 30,000 foot view anywhere?
I don’t think the algorithms are, but a general overview of the entire pipeline is well described in https://odmbook.com (disclaimer: I wrote it).
