小型全Stokes矢量分孔径偏振相机的图像处理技术与精度提升研究
Research on image processing techniques and accuracy improvement of a compact full-Stokes vector division-of-aperture polarization camera
摘要
Abstract
To enhance the measurement accuracy of a compact full-Stokes vector aperture-division polarimetric camera,a series of polarimetric image processing techniques have been proposed and established.These techniques specifically encompass dark current correction,bilateral filtering for noise reduction,image distortion correction,polarization parameter calibration,and channel image registration,followed by experimental research on polarimetric imaging.The results demonstrate that these techniques effectively mitigate the impact of various non-ideal factors on the camera's imaging process.After image processing,the reprojection errors of the four polarization channels are all less than 0.2 pixels,and the average structural similarity index(SSIM)between the four polarimetric sub-images is improved by 15.2％.This signifies a significant enhancement in the accuracy of polarimetric information measurement.关键词
