Websensor_msgs::PointCloud：该类型属于较早的版本，以逐渐弃用。 sensor_msgs::PointCloud2：目前常用的点云数据类型. PCL 中的点云数据类型 “>pcl::PointCloud:点云以模板的形式定义，可以用pcl定义好的，也可以自定义. 本文旨在分享如何将 sensor_msgs::PointCloud2转换为 pcl::PointCloud。 Webpcl::PointCloud ::Ptr cloud_xyz(new pcl::PointCloud ); sensor_msgs::PointCloud2 cloud_msg; pcl::toROSMsg(*cloud_xyz, cloud_msg); 总之，PCL提供了许多方法来实现不同点云类型之间的转换，开发者可以根据自己的需求选择合适的方法。

Websensor_msgs::PointCloud The first adopted point cloud message in ROS. Contains x, y and z points (all floats) as well as multiple channels; each channel has a string name and an array of float values. WebThe sensor_msgs/PointCloud2 message type is the standard output type from many 3d perception sensors, including LIDAR and stereo cameras. As imaging radar begins to approach the point density of these sensors, it makes sense to convert to this native ROS message type for use with existing perception stacks.
