【摘要】：针对传统的非均匀校正算法难以校正偏振成像的非均匀问题,提出了一种新的矩阵校正算法。分析了偏振成像与非偏振成像的非均匀性的不同表现,阐述了微偏振片阵列成像的非均匀产生机理,指出了采用非偏振成像非均匀校正方法的失效原因。在构建偏振成像系统对入射偏振光源的响应模型基础上,提出了矩阵校正法。实验部分给出了矩阵校正法对均匀偏振场本底图像和信息丰富场景图像的校正效果,定量分析结果表明,矩阵校正法将均匀本底图像的非均匀性降至校正前的10%左右。
[Abstract]:A new matrix correction algorithm is proposed to solve the problem that the traditional nonuniformity correction algorithm is difficult to correct the nonuniformity of polarization imaging. The different performances of nonuniformity between polarization imaging and non-polarization imaging are analyzed. The mechanism of nonuniformity in micro-polarizer array imaging is expounded. The failure reasons of nonuniformity correction method for non-polarization imaging are pointed out. On the basis of constructing the response model of polarization imaging system to incident polarized light source, a matrix correction method is proposed. In the experiment part, the correction effect of the matrix correction method on the background image of uniform polarization field and the scene image with abundant information is given. The quantitative analysis results show that the matrix correction method can reduce the non-uniformity of the uniform background image to about 10% of that before the correction.
