基于图像传感器的高精度误差标定方法VLP

High Accuracy VLP based on Image Sensor using Error Calibration Method

Shihuan Chen, Weipeng Guan

摘要:

在本文中,可见光定位(VLP)的接收机采用商业图像传感器被认为是。本文首先分析了采用图像传感器的VLP系统的理论极限和误差来源。在此基础上,建立了基于接收机运动的VLP定位模型,并进一步提出了两种新的误差校准算法,即旋转校准法和色散圆校准法。旋转算法估计图像中的旋转中心,而不是将图像中心视为旋转中心,从而减少定位误差。对于色散圆,它可以抵消定位计算中不同坐标转换产生的偏移误差。实验结果表明,本文提出的方法的平均定位误差可以降低到0.82cm,达到了VLP领域的先进水平。

英文摘要:

In this paper, visible light positioning (VLP) where the receiver adopts a commercial image sensor is considered. We firstly analyze the theoretical limits and error source of the VLP system using image sensor. And then, we develop a VLP positioning model on the receiver movement and further propose two novel error calibration algorithms, namely Rotation Calibration Method and dispersion circle calibration method. The rotation algorithm estimates the rotation center in the image instead of treating the image center as the rotation center, leading to reduced positioning error. For the dispersion circle, it can offset the shift error created by the conversation between different coordinate during the positioning calculation. According to the experimental results, the average positioning error of the proposed methods can be reduced to 0.82cm, which achieve state-of-the-art in the VLP field.
