MatchMover extracts all camera parameters from information contained in a film sequence. From a set of 2D points automatically tracked through an image sequence, MatchMover computes the following:
- The camera path and all the camera internal parameters such as zoom and distortion.
- The coordinates of the 3D points that project onto the 2D point tracks.
- The motion of independent moving objects.
A preview sequence with additional computer-generated objects in the scene can be generated to check the quality of the tracking result. If necessary, post filtering can be used to smooth the computed camera path. The camera data is then ready to export to an animation or compositing program.
With MatchMover, no geometric data from the set or from the camera is required, but they can be used for faster computation and stronger constraints. Integrated high-end 2D tracking modes enable very precise camera reconstruction. MatchMover works with any type of camera equipment, any image resolution, and can process any camera path in the most commonly used image formats.
Matchmoving is the computation of the global 3D geometry of a scene including camera path, internal parameters, and moving object.
By exporting the real 3D camera path and parameters to animation software, the position and motion of virtual cameras can be accurately established.
With the motion of the virtual cameras, new, matched image sequences can be created whose virtual objects are seamlessly composited into live action footage.
Matchmoving lets you accurately place 3D objects into a film, video or image sequence. For virtual objects to appear as part of the scene, the objects have to be rendered by a virtual camera whose motion exactly matches the motion of the actual camera that shot the film.
Using Autodesk MatchMover you can generate the exact camera parameters that match the motion of the actual camera used in the sequence.
