| Research Abstract |
We aimed at proposing visual simultaneous localization and mapping(VSLAM) system which is adaptive and flexible to large changes of scenes and views in image sequences. We deeply studied several feature tracking approaches and figured out that SURF feature tracking is an appropriate choice for accomplishing 3D reconstruction with our VSLAM system. Further, we extended the efficiency of camera tracking algorithm using the key-frame selection algorithm based on a fast image indexing method. Experimental validations and performance evaluations w. r. t. the state of the art structure-from-motion system have achieved on challenging real image sequences acquired under various scene and camera conditions.
