Description

ACTS is an automatic camera tracking and depth recovery system which can efficiently and stably recover camera motion as well as dense depth maps and 3D scene structure from videos and film sequences. It is free for non-commercial research and educational use. If you use this executable for your academic publication, please acknowledge our work. This program is tested on Windows XP, Server 2003, Win7, but is still not guaranteed to be bug-free and work properly with all versions of Windows. You are welcome to report any suggestions or bugs. We will actively update the program. Please email Guofeng Zhang if you have any questions.

Structure-from-Motion is a cornerstone for many other computer vision tasks, such as 3D reconstruction, video-based rendering and video editing. In the future, we will actively update ACTS and add more and more advanced or extra functions along with our published papers.
