Feasibility of integrated GNSS/OBD-II/IMU as a prerequisite for virtual reality

Abstract

To build accurate GIS (Geographical Information System) in urban area for advance virtual reality, accurate positioning is one of most important prerequisites. For this purpose, GNSS (Global Navigation Satellite System) is attractive since it can provide absolute coordinates to any object located on earth. However, accurate positioning is not a simple problem since any single GNSS cannot provide sufficient the number of visible satellites in urban area. To improve positioning availability in urban area for advanced virtual reality applications, this paper proposes a hybrid positioning method integrating a GPS/BeiDou receiver, an OBD-II (On-Board Diagnostics-II) device, and a MEMS IMU (Micro Electro Mechanical Systems-Inertial Measurement Unit). By an experiment result with field-collected actual measurements, the feasibility of the proposed method is evaluated.
