一种基于智能手机的可见光室内信标定位方法
A Scheme of Indoor Visible Light Beacon Positioning Based on Smartphone
摘要
由于室内环境的特殊性, 传统定位技术在室内的应用受到诸多限制。针对室内定位问题, 提出了一种基于智能手机的可见光室内定位方案。该方案利用室内LED(发光二极管)照明光源作为定位信标, 通过智能手机内置摄像头的卷帘快门工作方式, 接收LED照明光源发出的可见光调制信号, 结合手机应用软件内的图像处理算法提取信标信息, 从而实现智能手机可见光定位功能。实验结果验证了该方案的可行性及有效性。
Abstract
The application of traditional positioning technology is limited because of the particularity of indoor environment. In order to solve indoor positioning problem, a scheme of indoor visible light beacon positioning based on Smartphone is proposed. In this scheme, locater beacons are sent out by indoor Light Emitting Diode (LED) light source and the visible light signal is received by exploiting rolling shutter effect of the camera embedded in Smartphone. Indoor visible light positioning is realized by the information in locator beacon which is extracted by the image processing algorithm in Smartphone application. The result of experiments is verified to be feasibility and effectiveness in this scheme.
