碩士 / 國立交通大學 / 電機與控制工程系所 / 96 / In this thesis, an active vehicle navigation system integrating wireless networks, intersection images and traffic information is proposed. In general, the conventional navigation system plans the shortest path without considering the real traffic status of the road. That is to say, the planned route might be in the traffic jam. Moreover, the car surveillance system usually gives the alarm as soon as the car is stolen or the abnormal event is happened by sending warning messages to the driver, which can not provide an immediately assistance. In order to solve the problems addressed, the proposed system is build in the TI OMAP5912 platform equipped with a GPS receiver, a USB camera, a touch screen and a wireless module. By using the map matching and map rotation algorithm, the system provides accuracy positions of the car in the map and good quality of map display. For active path planning, Dijkstra's shortest path algorithm is enhanced to provide an optimum evaluation with the actually real-time jammed traffic information. Furthermore, to supply the driver with the mobile surveillance and burglarproof tracking, the navigation maps and images inside the car are delivered to the mobile device via 3G wireless networks anytime and anywhere. Finally, real-time streaming images in the intersection are transmitted via 3G wireless networks to the driver to realize the true traffic status.
