提出了一种测距辅助的可见光指纹定位(RAFL)方法,基于测距方法,根据多组光源初步确定定位目标的位置范围,采用双线性插值算法构建定位区域指纹,在定位目标范围内进行指纹匹配,最终获得目标的实际位置。研究结果表明,所提方法具有较强的抗干扰性,能够有效提高定位精度。

A range-assisted visible light fingerprint localization (RAFL) method is proposed. Based on the ranging method, the position range of the positioning target is preliminarily determined according to the multiple sets of light sources. Then the bilinear interpolation algorithm is used to construct the localized area fingerprint and the fingerprint matching is carried out within the target range. The actual location of the target is finally obtained. The research results show that the proposed method has a strong anti-interference ability and can effectively improve the positioning accuracy.
