RDSLAM: Robust Dynamic Simultaneous Localization and Mapping

 

RDSLAM system

RDSLAM is a real-time simultaneous localization and mapping system which allows parts of the scene to be dynamic or the whole scene to gradually change. Compared to PTAM, RDSLAM not only can robustly work in dynamic environments, but also can handle a larger scale scene (the number of the reconstructed 3D points can be tens of thousands). It is the basis for many applications, such as real-time 3D reconstruction and augmented reality.

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. Besides camera motion, it also can recover accurate and dense depth maps now.

We will actively update the program and add more and more advanced or extra functions along with our published papers in the future.
