For users that need to export data or use it externally, some documentation is needed

  • format of feature files
  • format of matches files
  • sfmdata is kind of self-explanatory (being a json) although it is worth mentioning that
    • the focal length is in mm (and how to get the pixel value that everybody else uses)
    • the principal point is an offset wrt the principal point
    • observations are stored in distorted coordinates (original extracted features)
    • the poses are stored as R and C, with C being the center of the camera, so that one needs to compute t = -RC to create the pose matrix
    • the order with which matrices are stored (column/row major) --> it should be column-major, default in eigen https://eigen.tuxfamily.org/dox/group__TopicStorageOrders.html
  • the format required for the masks (naming must be the same as the original image or its id?)
