Model-Based Camera Tracking in Dynamic Environments

Abstract - Model-based camera tracking is a technology that estimates a precise camera pose based on visual cues (e.g. feature points, edges) extracted from camera images given a 3D scene model and a rough camera pose.

Issues

1. How to fuse both cues: edges (line information) and points (texture information)
2. Fast and robust tracking of both cues
3. Stable and flexible camera tracking in dynamic environment
4. How to track less-textured 3D objects in cluttered backgrounds
