Compared to 2D navigation, 3D navigation requires much better performance of locating and heading. In an urban environment, the signals from a built-in GPS on a smart phone are always so weak that it causes considerably low position and heading accuracy. To address this issue and improve the user experience, two contexts, Navigation and Look-Around, are defined in 3D personal navigation. The following...
Recently, research towards using 3D city models for personal navigation has been rapidly increasing. In this paper, an approach for 3D city model reconstruction for the application of mobile phone-based navigation is presented, which is based on data collected from vehicle-based mobile mapping system (MMS). Our method is performed based on three objectives: small model size, perfect accuracy control...
The vehicle-based laser scanning (VLS, also known as mobile mapping) is a new technology, which is currently under development for creating 3D models of the surrounding environment. VLS is based on the integration of GPS, IMU, laser scanner and preferably digital cameras mounted on top of a moving platform, i.e. a car in most applications. VLS is a logical development after the first operative Airborne...
