碩士 / 國立交通大學 / 資訊科學系 / 89 / An effective vision-based approach to security patrolling in building corridors using vehicle navigation is proposed in this study. A commercial vehicle mounted with multi-cameras is designed to navigate and patrol in building corridors. The information of the location of the vehicle and the environment conditions can be transmitted to a security monitor site through the wireless network. Two modes of vehicle guidance, remote control and automatic guidance, are proposed for use in navigation session. During navigation, the vehicle system detects unexpected objects. A distance-weighted correlation measure, computer vision, and image sequence techniques, are used to discriminate between stationary and moving objects. An obstacle avoidance process is performed to achieve collision-free navigation. An object tracking process is performed to follow moving objects. In addition, door opening and disappearance of existing objects can be detected, and the environment images are then compressed and transmitted to the monitor site through the wireless network. Experimental results show the feasibility of the proposed approach and system.
