Full strengths for COLMAP
  • It covers the whole structure-from-motion and multi-view stereo path in one program, with both a graphical interface and command-line tools, and it works on ordered and unordered image collections.
  • LiDAR features need a LiDAR-equipped iOS device
  • Processing relies on the service rather than your own machine
  • Reconstruction is slow and wants a capable GPU, and the quality of the result depends heavily on how…
Full limitations for COLMAP
  • Reconstruction is slow and wants a capable GPU, and the quality of the result depends heavily on how carefully the source photographs were shot.
