Indoor and Outdoor Precision Positioning System Based on Beidou Difference and UWB

Abstract

Although the map services given priority to baidu map or Google map have met the most people for outdoor location information for navigation and position requirements, however, as the rapid development of areas such as automatic drive, Internet of Vehicles, the demand for indoor and outdoor high-precision position becomes more and more urgent. The 3d visualization technology based on virtual reality (VR) has been widely used in various fields of social life, such as environment, transportation and construction of digital city. This paper mainly introduces the following three key technologies: (1)The acquisition and application of outdoor high-precision location; (2)The design and implementation of indoor 3d virtual interactive system; (3)Seamless switching technology between indoor and outdoor maps.
