碩士 / 國立交通大學 / 電控工程研究所 / 100 / Currently, most navigation systems not only integrate real-time traffic information and location-based services, but also provide simulative 2D/3D maps for vehicle navigation. However, drivers may be distracted due to the frequent search for information and identification of digital maps and real scenes, which may lead to a dangerous situation. Moreover, conventional navigation systems plan the shortest path without considering the real traffic status of roads. Drivers may spend more time to arrive their destinations, when the planned routes are actually in the traffic jam.
This thesis proposes an active vehicle navigation system integrating real-time traffic information and images to solve the addressed problems. The proposed system is built in the DM3730 embedded platform, equipped with a GPS module, a CCD camera module, and an electronic compass. An augment reality navigation is designed to assist drivers efficiently know the guidance of the navigation path. In addition, the nearby real-time traffic information and images are actively provided according to the current location of the driver, which makes the driver easily know the traffic information anytime and anywhere. For active path planning, not only an enhanced A* shortest path algorithm is provided by integrating the real time and history traffic information, but also the shortest path planning for the global region and the shortest time planning for the local region are automatically served for drivers.
