jetson nano ubuntu18.04 ros1和ros2安装大象机械手mycobot系列 的ROS 包
按照上述连接中的教程一步步安装,到 构建工作区中
mycobot_ros
的代码这一步,会出现错误,如下:

解决办法:
这不是因为我们编写的程序有误,而是NVIDIA的32.3.1image自带的是opencv4版本,把opencv命名成了opencv4
修改方法:只需修改上述路径中的cv_bridgeconfig.cmke文件,将100行附近的两个opencv改成opencv4即可(注意,只需要改动单独一个的opencv,前面有连字符的opencv不需要改动)
注意:如果jetson nano的版本自带的opencv是3版本,可能不会出现此问题
修改命令: sudo gedit /opt/ros/melodic/share/cv_bridge/cmake/cv_bridgeConfig.cmake
修改成opencv4即可
如何查看本机opencv版本?
第一步:输入
cd /usr/bin
进入目录
然后输入:
./opencv_version
