图像拼接

介绍

此Repo是有关图像拼接的毕业设计的代码实现

进度

2018年3月24日:

利用Python的OpenCV库实现了简单的图像拼接,示例:

左图 右图 结果
3-left 3-right 3-surf
19-left 19-right 19-SIFT

2018年4月1日:

阅读OpenCV的ORB代码,并进行改动并编译。67d825

关于ORB的分析见orb解析

2018年4月11日:

利用K-means算法进行特征点匹配的筛选。fb4d88

结果:不理想

2018年4月12日:

局部变换矩阵,在整体变换矩阵的基础上对与偏心过大的点进行单独的变换。ca567e

结果:不理想

2018年4月24日:

实现python版本的RANSAC算法,并在其基础上对其进行改进。e36663

结果:实现了和OpenCV的cv2.findHomography函数功能基本一致的结果。

2018年4月26日:

利用遗传算法对RANSAC进行改进。ce3a8b

结果:能初步达成效果,但最终效果不及RANSAC

2018年4月27日:

试图使用变换矩阵作为遗传算法的基因。af87e9

结果:没有明显提高。

TODO

  • 改进ORB的旋转不变性
  • 改进ORB的匹配或者特征点选取方式以使其基金SIFT的拼接效果
  • 在RANSAC算法的基础上改进特征点选择方式使得ORB的特征选取更有代表性
