摘要
可见光通信定位(VLP)技术具有低成本、高精度、无电磁干扰、部署便捷、兼顾通信定位和照明的优点,在室内定位领域展现出良好的应用前景。本文首先分别总结了基于可见光通信的成像和非成像室内定位方法,分析和讨论了两种方法的关键技术、研究进展及应用情况;然后,提出了一种基于自相关序列的VLP光源匹配识别方法,并介绍了一种基于普通成像传感器和矩形平板光源的定位系统构建方法;最后,对室内VLP技术的研究发展方向进行了展望。
The technology of visible light positioning(VLP)has the advantages of low cost,high precision,no electromagnetic interference,convenient deployment,and the advantage of taking into account both communication positioning and lighting which makes this technology has potentially useful application prospects in the field of indoor positioning.In this paper,two indoor positioning methods based on visible light communication(VLC)called imaging and non-imaging method are summarized,meanwhile,their key technologies,research development,applications and trend are analyzed and discussed.A VLP light source matching identification method based on autocorrelation sequence is proposed,whats more,a method of constructing a positioning system based on the common imaging sensor and rectangular flat-panel light source is introduced.Finally,the research and development direction of indoor VLP technology is prospected.
