in the vein of @smathermather-cm’s recent exploration of mapping all the things with ODM, I’ve been tinkering with towers and trees. These are traditionally hard topics for reconstruction (in my experience, maybe I can learn something!) - so here is a first cut attempt. The flight pattern is lots of circles at different heights, plus some with an upward looking camera (increasing the exposure offset so that detail is captured where there’s no direct light).
My ODM settings were:
--camera-lens brown --dem-resolution 2 --orthophoto-resolution 2 --mesh-octree-depth 12 --depthmap-resolution 1200
…I can see that it’s not quite there, the tower (a single pipe) is a bit wonky; and the solar panels are not flat. I’m running again now with
--depthmap-resolution 2048 --opensfm-depthmap-method BRUTE_FORCE to obtain more points, and will post results.
Anyone had success with modelling similarly complex objects? what settings did you use?
