室内导航定位技术的发展综述

Development of Indoor Navigation and Positioning Technology

随着城市建设进程的加快,人们对室内导航定位技术的需求愈发明显,为该技术的发展提供了广阔的应用空间。文章从基于单一传感器与基于多传感器两个方面对当前一些主流的室内导航定位技术进行了介绍,包括低功耗蓝牙技术、超声波技术、Wi-Fi技术、超宽带技术、红外技术、视觉技术、微惯性器件及其组合技术等。最后,总结了这些技术存在的一些不足之处,并展望了其在多领域的应用前景。

With the acceleration of urban construction,people's demand for indoor navigation and positioning technology becomes more and more obvious,which provides a broad application space for the development of this technology.This paper introduces some mainstream indoor navigation and positioning technologies based on single sensor and multi-sensor,including Bluetooth low energy technology,ultrasound technology,ultra-wide-band technology,Wi-Fi technology,infrared technology,vision technology,micro inertial devices and their combination technology.Finally,several shortcomings of these technologies are summarized,and their applica-tion prospects in many fields are prospected.
