摘要
针对基于电阻阵拼接的红外场景方法进行研究,先利用边缘融合进行图像拼接处理,得到一幅在重合部分存在亮度偏大的图像。对重叠部分每个像素的亮度进行加权处理,在此基础上进行各像素点的亮度叠加。使重合部分的像素点的亮度能够与非重叠部分较好融合过渡。电阻阵列的非均匀性问题也会使得拼接效果大打折扣,利用分段线性化的方法进行灰度非均匀性处理,得到最终的拼接效果图。经仿真验证,该方法简单快速,有效地校正了图像灰度非均匀性,并且能在保持图像清晰度的前提下,消除拼接缝,提高拼接图像的质量。
Abstract
The article directs at the infrared image mosaicing. Firstly, the image should be spliced with the edge fusion. But the brightness comes to be a big problem in the overlap part. The brightness of each pixel in the over-lap part is weighted by the distance to the nearest edge. Then add the weighted brightness of each pixel together in order to get the corrected brightness. The fusion effect is reduced because of the nonuniformity of resistor array. Correct the gray scale nonuniformity by subsection linear sparse and then obtain the final picture. Simply and fast the method works in the simulation. The image grey nonuniformity caused by imaging system is corrected effectively and the seam is eliminated. The quality of stitching images is also improved on the premise of keeping the image resolution.
