wget https://raw.githubusercontent.com/SebastianGrans/ROS2-Point-Cloud-Demo/master/config/config.rviz 进入launch子目录,并运行以下命令下载两个启动文件: wget https://raw.githubusercontent.com/SebastianGrans/ROS2-Point-Cloud-Demo/master/launch/pcd_publisher_demo.launch.py wget https://raw.githubuse...
然后定义了用于将sensor_msgs.msg.PointCloud2类型消息对象读取到numpy数组的read_points()函数。该函数有四个输入参数:第一个参数cloud用于指定要读取的PointCloud2消息对象变量;第二个参数field_names用于指定要读取的字段名称,默认值为None;第三个参数skip_nans用于指定是否不返回即跳过具有NaN值的点,默认为False,...
For this issue, I'm focusing on PointCloud2s, but I am also having the same problem with visualization of Path and Pose topics. This seems to be a bug, but if it is user error, I apologize in advance. Something seems to have changed (external to my unchanged setup) in the last mo...
