摘要

由于存在边缘视场的渐晕效应,造成SIP-DSWP 同时偏振成像系统的偏振信息重构存在偏差。为此,本文提出了一种通过分区仪器矩阵校正视场边缘效应的成像系统校正方法。通过对SIP-DSWP同时偏振成像系统3×3分区仪器矩阵的标定,进行了玻璃平板倾角的非接触检测实验。实验结果表明:图像边缘视场效应和噪声能够直接影响偏振成像及偏振信息(偏振度和偏转角)重构;分区仪器矩阵较平均仪器矩阵能够更准确地重构出目标场景的偏振信息,提高对透明玻璃平板倾角的检测精度,为后续偏振成像方法的研究和定量检测应用奠定了理论基础。

Abstract

Because of the vignette effect of the edge field viewing, deflection exists in the reconstruction of polarization information using polarization imaging system. Therefore, in this paper, we proposed an imaging system correction method. The method was realized by filed viewing effect correction using the partition instrument matrix. The non-contact testing experiment of the glass-plate angle was conducted by calibrating the 3×3 partition instrument matrix of the SIP-DSWP synchronous polarization imaging system. The result of the experiment shows that the imaging edge field viewing effect and its noise are likely to affect the reconstruction of polarization imaging and polarization information. Compared to the instrument matrix, the partition instrument matrix can reconstruct the polarization information of the target view more accurately, increasing the test accuracy of the transparent glass-plate angle and subsequently establishing an academic foundation for the study of polarization imaging and quantitative testing application.
