Visible light positioning (VLP) has been widely studied since it can provide high accuracy indoor positioning functionality with light-emitting diode (LED) beacons. However, existing VLP systems still suffer from high positioning latency and low robustness in practical scenarios. A robust and low-complexity image processing algorithm is proposed for LED region-of-interest (ROI) extraction and tracking, which contributes to handle various harsh situations and support accurate VLP with low positioning latency. Experimental results show that the proposed LED-ROI scheme can achieve an average tracking accuracy of 0.46 cm and better real-time performance and robustness compare with the others current LED-ROI methods.

强大的LED感兴趣区域跟踪功能，以低复杂度实现可见光定位

由于可见光定位（VLP）可以通过发光二极管（LED）信标提供高精度的室内定位功能，因此已经得到了广泛的研究。但是，在实际情况下，现有的VLP系统仍然遭受高定位延迟和低鲁棒性的困扰。提出了一种鲁棒且低复杂度的图像处理算法，用于LED感兴趣区域（ROI）的提取和跟踪，有助于处理各种恶劣情况并以低定位延迟支持准确的VLP。实验结果表明，与现有的其他LED-ROI方法相比，所提出的LED-ROI方案可以实现0.46 cm的平均跟踪精度，并具有更好的实时性能和鲁棒性。
