最佳答案
有几个不同的问题可能会导致此问题。首先，这可能是由于安装了多个 dynamic_reconfigure 造成的。在您的系统上。您还应该确保您是 CMakeLists.txt包括image_geometry在对 find_package 的调用中.
关于python - 我在 ROS realsense D435 相机上也遇到了这个错误。我写的代码 "roslaunch realsense2_camera rs_rgbd.launch"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/69097063/
