摘要
近年来,基于位置服务的需求日益增大,针对室内场景的定位技术发展迅速。我国《测绘地理信息科技发展“十三五”规划》也明确提出开展室内外无缝导航与智慧时空技术的研究,从而形成室内外一体化位置服务体系。建立一种稳定可靠、高精度、低成本、易于维护的室内导航系统成为研究热点与挑战。从室内三维高精度定位、室内三维精细化模型构建、三维场景下的路径规划3个方面阐述了室内定位技术国内外研究现状,并分析了室内定位技术的研究难点和发展趋势。
In recent years,with the increasing demand for location-based services,positioning technology for indoor scenes has developed rapidly.China's The 13th Five Year Plan for the Development of Surveying and Mapping Geographic Information Technology also clearly proposes to carry out the research on indoor and outdoor seamless navigation and intelligent space-time technology,so as to form an indoor and outdoor integrated location service system.Establishing a stable,reliable,high-precision,low-cost indoor navigation system has become a research challenge.This paper briefly expounds the research status of indoor positioning technology at home and abroad from three aspects:indoor 3Dhigh-precision positioning,indoor 3Dfine model construction and path planning under 3Dscene,and analyzes the research difficulties and development trend of indoor positioning technology.
