摘　　要：文章提出一种基于发光二极管(Light Emitting Diode,LED)收发的室内人员占用检测方法,其采用广义似然比检验(Generalized Likelihood Ratio Test,GLRT)以实现鲁棒的检测性能。实验结果表明,在固定光强下无其他目标时,所提出的方法可以实现98%以上的检测准确率。在背景光强变化和感知区域内存在其他目标时,可实现95%以上的检测准确率。相比支持向量机(Support Vector Machine,SVM)方法,所提方法更鲁棒且需要资源更少。This article proposes an indoor personnel occupancy detection method based on light emitting diode(LED)transceiver,which adopts the generalized likelihood ratio test to realize robust detection performance.Experimental results show that the proposed method can achieve a detection accuracy of over 98%when there are no other targets under fixed light intensity.Under the variation of background light intensity and the presence of other targets in the sensing region,a detection accuracy of over 95%can be achieved.Compared to the support vector machine(SVM)algorithm,the proposed method is more robust while requiring fewer resources.
