【摘要】：針對(duì)航空核線影像的稠密匹配問(wèn)題,該文提出了一種基于控制點(diǎn)與RGB三色置信傳播模型的多通道置信傳播算法。該算法利用點(diǎn)特征匹配算子提取影像的部分同名點(diǎn)作為區(qū)域控制點(diǎn),隨后將RGB 3個(gè)顏色分量都作為置信傳播模型的獨(dú)立基礎(chǔ)變量,同時(shí)增加鄰域像素點(diǎn)對(duì)的顏色差異的貢獻(xiàn)。兩組核線影像匹配實(shí)驗(yàn)結(jié)果表明,所提算法在使用較少參數(shù)的情況下,降低了同名點(diǎn)存在顏色差異造成的干擾,利用置信傳播原理提高了同名點(diǎn)的匹配正確率,能有效進(jìn)行航空核線影像的逐像素密集匹配。
[Abstract]:A multi - channel confidence propagation algorithm based on control point and RGB three - color belief propagation model is presented in this paper . The algorithm uses the point feature matching operator to extract part of the same point as the regional control point , then the RGB 3 color components are used as the independent foundation variables of the confidence propagation model , and the color difference of the neighborhood pixel points is increased . The results show that the proposed algorithm can reduce the interference caused by the color difference in the point of the same name , and improve the matching accuracy of the same point by using the confidence propagation principle , and can effectively carry out the pixel - by - pixel intensive matching of the aerial nuclear image .
