Consequently, a robot has to localize its position and build map simultaneously in unknown environments. In this thesis, we study SLAM (simultaneously localization and mapping) of mobile robot employing monocular vision and odometer. Moreover, experiments were applied to evaluate the performance of the proposed mechanism. First the vision picture was processed to derive the objects’ vertical edge landmark. The relative coordinates were than defined and reduced from three-dimension to two-dimension to simply computation. Consequently, the robot’s trajectories derived using the data of odometer were applied to build the robot’s dynamic model. In this study, the extended Kalman filter was employed to eliminate the accumulated error from odometer measurement and noise. The states of mobile robot and landmarks were estimated and updated continuously. The localization of mobile robot was achieved through the matching of landmarks. Moreover, laser range finder was utilized to draw the map of unknown environment. Guan-Chun Luh 陸冠群 2009 學位論文 ; thesis 45 zh-TW
