> ![Image](https://github.com/user-attachments/assets/246b65cb-4dcb-49b9-b150-4e8eb3840c77)这样够清楚吗 thanks 我没有认真看到 `meas_vec(i) = -ptpl_list_[i].dis_to_plane_;` & `auto vec = state_propagat - state_; // x_pred - x_k` 的含义

顺序可以参考这个函数 https://github.com/hku-mars/FAST-LIVO2/blob/7e884601bcc193e3eabaf1958d4c14cdcff80212/include/common_lib.h#L167-L180

我也遇到这个疑问,看了VoxelMap也是这么写的,可以参考 https://github.com/hku-mars/VoxelMap/issues/15
