非常感谢您开源的OAFD算法,我安装了双系统,买了一台tello,环境安装好了,程序跑起来以后发现坐标系好像有问题,就是tello向前运动的时候,rviz里是在向天上运动,点云也是在朝天空的方向,请问是我哪里设置的不对吗?麻烦了,耽误您的宝贵时间!

1.一种可能是单目初始化错误 坐标系是建立在ORB_SLAM3提供的坐标系之上的。 而单目SLAM坐标系全靠单目初始化来确定, 在初始移动有旋转,环境有大量反射(大理石地板之类的)之类的情况可能会导致初始化错误估计坐标系方向。
2.一种就是单纯的坐标系转换出错,不过不知道原因是什么 ORB_SLAM3 纯视觉不带惯性的话,坐标系Z轴垂直于画面。而ROS Z轴垂直于重力方向 映射到ROS坐标系需要转换,可以见 https://github.com/geturin/orb_slam3_ros_wrapper/blob/4f1aaffa1c4eae9ad9680047bd867650f673989e/src/common.cc#L83
出错的原因我推测是ORB_SLAM3版本问题,不过找不到原因也没关系 你可以尝试修改上面的坐标系变换矩阵。 或者直接使用ros_tf来追加坐标系转换。感觉这样会比排查原始问题来得简单。
Sorry, something went wrong.
