【摘要】：針對傳統(tǒng)的非均勻校正算法難以校正偏振成像的非均勻問題,提出了一種新的矩陣校正算法。分析了偏振成像與非偏振成像的非均勻性的不同表現(xiàn),闡述了微偏振片陣列成像的非均勻產(chǎn)生機(jī)理,指出了采用非偏振成像非均勻校正方法的失效原因。在構(gòu)建偏振成像系統(tǒng)對入射偏振光源的響應(yīng)模型基礎(chǔ)上,提出了矩陣校正法。實(shí)驗(yàn)部分給出了矩陣校正法對均勻偏振場本底圖像和信息豐富場景圖像的校正效果,定量分析結(jié)果表明,矩陣校正法將均勻本底圖像的非均勻性降至校正前的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.
