【摘要】：高精度室内定位在很多场合的实用性和必要性日趋显著,其应用前景广阔,已成为研究前沿。基于微惯导技术的室内定位,是目前最为精确和有效的一项定位技术,但由于微惯导测量组件存在不可避免的漂移现象,使其无法长时间独立用于目标的定位。在此背景下,提出了一种基于微惯导(Micro-Inertial Navigation System,Micro-INS)与可见光通信(VLC)系统相结合的定位方法。在该方法中,首先通过微惯导测量组件进行航位推算,然后利用获取的VLC信号对微惯导系统的位置信息进行校准,补偿微惯导系统的定位累积误差。定位实验结果表明,文章所提出的方法可有效地提高系统定位精度,实现室内的长时间精确定位。
[Abstract]:The practicability and necessity of high-precision indoor positioning are becoming more and more obvious in many occasions, and its application prospect is broad, which has become the research frontier. Indoor positioning based on micro-inertial navigation technology. It is the most accurate and effective positioning technology at present, but because of the inevitable drift phenomenon of the micro inertial navigation measurement module, it can not be used independently for a long time to locate the target. A micro-inertial Navigation System based on micro-inertial navigation system is proposed. Micro-INS) is a positioning method combined with visible light communication (VLC) system. In this method, the microinertial navigation module is first used to calculate the position. Then the position information of the micro inertial navigation system is calibrated by using the acquired VLC signal to compensate the cumulative error of the positioning of the micro inertial navigation system. The method proposed in this paper can effectively improve the positioning accuracy of the system and realize long time accurate positioning in the room.
