博主您好,感谢博主的工作并开源,我最近在学习EKF相关的知识,你的文章和代码是一个很好的学习材料。但是在我尝试运行代码的时候,发现aruco marker无法成功检测, 我尝试了

1.OpenCV-3.4.15 + contribute模块;
2.OpenCV-3.4.15-contribute扣出aruco模块单独编译成库。
3.OpenCV-3.1.0 + contribute模块;

结果均是能编译成功,但是无法检测到markers。 想咨询一下博主aruco 相关部分有参数的变动吗?

另外,我想咨询一下,知乎文章中,公式(18),求解\Sigma_{mm}这里为什么要乘一个\Sigma_\xi?

我的理解是\Sigma_{mm}是新加入的地图点对新加入的地图点的求导,而\Sigma}_\xi是原状态量与地图点的协方差,不太明白他们之间有什么关系。

谢谢博主,期待博主的回复。

在OpenCV-3.4.15环境下,博主在代码中没有使用生成好的dictionary,每次运行代码都会新创建一个dictionary,这样可能导致markers匹配不到。
我不清楚OpenCV-3.1.0下有没有这个问题。
