摘要

大多数现有的室内定位系统都是电池供电的，并使用射频(RF)信号的变化来定位物体。在本文中，我们提出了LocaLight:一种无需电池的室内定位系统，它通过跟踪物体投射的阴影来使用可见光来定位物体。通过感知由于阴影的存在而引起的环境光强度的下降，locallight将物体定位。由于阴影的位置可以预测，因此可以通过仔细定位光传感器和顶灯来将物体定位在敏感区域。我们的初步结果表明，LocaLight达到了与许多使用射频的最先进解决方案相当的精度。

Poster Abstract: LocaLight - A Battery-Free Passive Localization System Using Visible Light

Most existing indoor localization systems are battery-powered and use the changes in Radio Frequency (RF) signals to localize objects. In this paper, we present LocaLight: a battery-free indoor localization system that localizes objects using visible light by tracking the shadow they cast. By sensing a drop in the intensity of ambient light caused by the presence of a shadow, LocaLight localizes the object. Since the position of the shadow can be predicted, it is possible to localize the object in a sensitive area by carefully positioning the light sensors and the overhead lights. Our initial results suggest that LocaLight achieves an accuracy comparable to many of the state-of-the art solutions that use RF.
