碩士 / 國立聯合大學 / 電子工程學系碩士班 / 106 / The main purpose of this paper is to use the Global Positioning System (GPS), Wi-Fi, the Smartphone with sensor and Dijkstra's algorithm to achieve National United University (NUU) campus navigation system. The campus navigation system will track the user's current location and to find the shortest path for desired location. This system is developed with Android Studio and test on the Android smartphone. The campus navigation system can be divided into the navigation and the positioning systems. First, the navigation system will plan the shortest path by using the Dijkstra's algorithm according to the user’s destination. The navigation routes involve both of indoor and outdoor paths. Second, the positioning system tracks the user’s location and determines the user’s location is indoor or outdoor. Indoor positioning system uses of Wi-Fi signal strength in the fingerprinting and inertial positioning with accelerometer, gyroscope and magnetometer. However, outdoor positioning system uses of GPS on NUU campus map. For outdoor navigation, Google map will be involved and it covers entire NUU campus. In our experiment, we used multi-scale method to solve the problem of map distortion. Experiment results showed that our NUU campus navigation system has a good performance to achieve the goal of campus navigation.
