In the example below we use the function to compute the difference between two point clouds. For example, you may publish a pcl::PointCloud in one of your nodes and visualize it in rviz using a Point Cloud2 display. For comparison of field names, "rgb" and "rgba" are considered equivalent However, if the order and/or number of non-skip fields is different, the skip fields are dropped and non-skip fields copied selectively. 2-D image styles usually come from depth sensors or stereo cameras. Not sure if it was just me or something she sent to the whole team. const PCLPointCloud2 & rhs ) Add a point cloud to the current cloud. For ways that are compatible in C++, I recommend reading from http://wiki.ros.org/pcl_ros, which describes that: pcl_ros extends the ROS C++ client library to support message passing with PCL native data types. Finally, for example, what is 171 value in data? The datatype tells whether the fields are float, uint16, int8 etc. Looking at the definition of PointCloud2, you see that the field that holds the "actual" point cloud data is a 1-dimensional array.
