摘要
低复杂度、低成本的定位方案的实现是提升可见光定位普及率的关键因素。为降低系统的复杂度,提升LED解码算法与定位算法的适用性,提出基于条纹像素宽度比的LED识别算法,通过计算LED成像区域中明条纹占据的像素行数与明条纹数量的比值,实现对LED的简单高效识别,同时依据双灯定位模型对旋转角进行简化计算。通过搭建一套低成本的定位系统进行实验验证,实验结果表明,在使用低复杂度算法的前提下,平均定位误差为7.02 cm,在90%的置信度下定位误差小于10 cm。
In order to reduce the complexity of the system and improve the applicability of LED decoding algorithm and positioning algorithm,a LED recognition algorithm based on stripe pixel width ratio is proposed to realize simple and efficient recognition of LED by calculating the ratio of the number of pixel rows occupied by bright stripes to the number of bright stripes in the LED imaging area,and the rotation angle was simplified according to the double LEDs positioning model.A low cost positioning system is built for experimental verification in this paper.The experimental results show that the average positioning error is 7.02cm under the premise of using the low complexity algorithm,and the positioning error is less than 10cm under 90%confidence.
