论文关于矩阵G的讨论 #17

Closed piggi999 closed 8 months ago

piggi999 commented 9 months ago

作者您好,非常感谢您开源的工作。最近在阅读您论文的时候我发现了一些可能的错误,您在Process Noise Compensation章节中所求取的G矩阵中蕴含的滤波器状态量表述似乎与论文说写的state vector=[x, y, x', y']不一致。按照论文中提供的G矩阵所求取的,应当是状态量[x, x', y, y']的过程噪声矩阵。如果以上我说错了什么或者误解了什么,请麻烦告诉我,再次感谢您的工作。

作者你好,我跟楼主有一样的疑问,如果论文中的顺序有误应该是[x, x', y, y'], 但是代码中我看kf.x表示的是[x, y, x', y'],而G表示的是[x, x', y, y']的过程噪声矩阵,这是不是代码有问题?还是G是有其他的含义?期待您的回复,感谢!

The code and the updated paper are aligned in their descriptions and implementations.

谢谢你的回复。请问你能再详细介绍一下图3中每个椭圆代表的含义吗? 为什么每个子图有两个相同颜色的图?

piggi999 commented 8 months ago

请问在消融实验中,没有使用Process Noise Compensation时,过程噪声矩阵是什么呀?

piggi999 commented 8 months ago

请问可以详细讲讲图4 c)中的实验做法吗?

corfyi commented 8 months ago

图3中每个椭圆代表的是检测值投影到地平面上的不确定性分布(二维高斯分布);消融实验中没有使用Process Noise Compensation时,过程噪声矩阵中的wx和wy没有针对相机运动程度进行调参。
