Vector Map Retrieval and Mapping Methods for the Individual Wearable GNSS Devices
摘要
Abstract
The individual wearable GNSS satellite devices,such as satellite watch,individual combat wristband,and GIS wearable terminal,typically have limited computing power and small storage capacities,which presents numerous challenges for implementing offline vector map data retrieval and mapping on these platforms.We proposed an offline vector map retrieval and mapping method suitable for wearable GNSS satellite devices,constructed an offline vector map format with multi-resolution storage for 3D information combination,and employed tile segmentation,dynamic loading,and realtime cropping algorithms to achieve efficient and lightweight offline vector data retrieval,mapping and rendering.The proposed method can load vector map data by 3D information combination within 20 km radius in 150 ms and complete data retrieval and mapping within about 2 s on Beidou satellite watch.关键词
