OpenDroneMap — Orthophotos and Textured Mesh

Good news to report, though I haven’t finished my own testing yet… but OpenDroneMap, which previously would just create point clouds from drone images, now also produces:

  1. Meshes!
  2. Textured meshes!
  3. Georeferenced textured meshes (if the exif data has geographic coordinates)
  4. Georeferenced orthophotos! (if the exif data has geographic coordinates)

Now, I’d like those ifs to go away, but that requires a bit of thoughtful interface work. In the mean time, give it a whirl on your data.

Work left to do:

  • Refine processing chain
  • Allow for input of GCPs for images without GPS in their exif
  • Blending / brightness correction, etc. of input images
  • Digital surface model output

See this branch on github for the whole package : https://github.com/OpenDroneMap/OpenDroneMap. A special thanks to Spotscale (http://www.spotscale.com/) for undertaking and executing this work.

(Just integrated with the main branch January 20, 2015)

These are Spotscale’s screenshots. I’m re-running on my own test machine for validation as we speak (so to speak):

Textured mesh of Seneca test dataset (flown by Fred Judson and others of ODOT with Sensefly Swinglet). Ignore curves-- they are all in the no-data areas.

    This looks excellent! What Linux distro do you use for the project?

    • Ubuntu is the distro of choice to date. I think it would work unmodified on Debian, but I don’t know that anyone has tried. So far it is just tested with 12.04 for texturing and orthophotos. I’ll be testing with 14.04 shortly.

  2. […] addition of orthophotos and textured mesh to OpenDroneMap (FYI, one word, and not OpenDroneMaps) https://smathermather.wordpress.com/2014/12/22/opendronemap-orthophotos-and-textured-mesh/ we have some more features in the pipeline. This is a deeper dive into architecture and future […]
