您好链接中odom_frame_是否应该是"/map"呢?https://github.com/RoboMaster/RoboRTS/blob/8d720a1ea0f42895ae7b3d518486f29fe9b7eff6/roborts_localization/localization_node.cpp#L137

I think the tf frames are correct as the parent of the base link frame in the tf tree should indeed be odometry. See here for more details about the design of localization scheme. Especially the figure in section 3.1.6.

@XinZhangk 恩恩我也发现了ros1 和 ros2 的amcl里初始化里都是odom_frame,因为那时可能还没有global_frame,但是接下来 odom transform * pose_old 就变成了map下的pose了呢?难道是一个估计吗?
