基于微偏振阵列成像的实时天空偏振光导航

Real-time sky polarized light navigation based on micropolarized array imaging

利用最新的IMX250-MZR微偏振阵列芯片,实现了60 FPS以上的实时天空偏振模式测量。在此基础上,对天空偏振角分布图像按照新的参考坐标系重绘,通过提取天空AOP分布图像的对称轴实现航向角的准确获取。实验测试结果表明:航向获取精度超过0. 1°,MATLAB环境下的系统实时导航频率大于20 Hz。

Real-time sky polarization mode measurement above 60 FPS is achieved using novel IMX250-MZR micro polarized array chip. On this basis,sky polarization angle distribution image is redrawn according to the new reference coordinate system,and the heading angle is accurately obtained by extracting the symmetry axis of the sky AOP distribution image. The experimental results show that the heading acquisition precision exceeds 0. 1°,and the system real-time navigation frequency in the MATLAB environment is higher than 20 Hz.
