This Julia package loads and saves Bundler files, used in the context of Photogrammetry and Struture from Motion.
The package is available in the Julia package repository and can be installed in the Julia REPL package mode:
pkg> add FileIO BundlerIO
The loading and writing is done via the FileIO.jl interface:
bundle = load("bundle.out")
The loaded data is in a
Bundle struct, that contains the points, cameras, views, and optionally colors and keypoints. The cameras are an array of
Camera objects from ImageProjectiveGeometry.jl, the 3D points are an array of
Point3 objects from Meshes.jl and the views are a
Dictionary with a tuple of
(camera_id, point_id) as keys and the pixel coordinates of the projection of that point into the image of that camera as value. The colors are an array of
Color objects from ColorTypes.jl. The keypoints are in a similar dict to the views, where the values are the ID of the SIFT keypoints that have been computed during SfM. This data is not always present and only kept for completeness.
