- | abstract = {In Augmented Reality applications, the human | + | |
- | perception is enhanced with computer-generated | + | |
- | graphics. These graphics must be exactly registered | + | |
- | to real objects in the scene and this requires | + | |
- | an effective Augmented Reality system to track the | + | |
- | user’s viewpoint. In this paper, a robust tracking algorithm | + | |
- | based coded fiducials is presented. Square | + | |
- | targets are identified and pose parameters are computed | + | |
- | using a hybrid approach based on a direct | + | |
- | method combined with the Kalman filter. An important | + | |
- | factor for providing a robust Augmented Reality | + | |
- | system is the correct handling of targets occlusions | + | |
- | by real scene elements. To overcome tracking | + | |
- | failure due to occlusions, we extend our method using | + | |
- | an optical flow approach to track visible points | + | |
- | and maintain virtual graphics overlaying when targets | + | |
- | are not identified. Our proposed real time algorithm | + | |
- | is tested with different camera viewpoints | + | |
- | under various image conditions and shows to be accurate | + | |
- | and robust.} | + | |
