手眼标定handeye-calib包使用问题
-
我看到小鱼大佬的这篇文章，基于ROS的机械臂手眼标定-基础使用https://blog.csdn.net/qq_27865227/article/details/113774717
使用里面github的代码时有些问题
请问base_hand_on_eye_calib.launch是手在眼上吗，
为什么第一个结果是end_link->marker，机械臂末端到标定板的位置不是变化的吗，
还有标定的结果为什么是base_link->camera，不是end_link到base_link->camera吗
非常感谢 -
@GHluck 把具体结果扔一个出来我瞅瞅，太久了给忘了

@小鱼
尝试了base_hand_on_eye_calib和base_hand_to_eye_calib，提示的结果除了数据以外都是一样的，不知道哪个是手在眼上，哪个是手在眼外
