ACTS: Automatic Camera Tracking System

ACTS is an automatic camera tracking system which can recover camera motion and 3D scene structure from videos and film sequences, providing the ease of automatic tracking. It can track all kinds of the camera motion efficiently and stably, which can be rotational or free-moving. Especially, the long sequences with varying focal length can be handled in a robust way. Currently, it is limited to recover the camera parameters and sparse 3D points only. We will actively update the program and add more and more advanced or extra functions along with our published papers in the future.
