Abstract:

利用单像素成像系统进行场景监视,对变化场景进行相同的信息调制,利用场景探测强度的差值作为测量值,采用压缩感知算法只需进行一次算法求解即可获取场景变化信息。使用数字仿真技术对提出的和传统方法进行场景变化信息反演获取对比实验。在简单的二值场景变化信息获取实验中,提出的方法在采样率为1%的情况下就可以获取准确的场景变化信息;对8bit灰度场景变化信息进行获取时,由于信息量变大,为了获取较高质量的场景变化信息需要的采样数增加,但在相同采样数下,提出的算法可以获得比传统方法更准确的结果。实验结果表明采用提出的方法可以在低采样率的情况下获取准确场景变化信息,并降低了获取场景变化信息计算复杂度,对单像素成像系统应用于场景监控具有参考价值。
