WebThe sensor_msgs/PointCloud2 is a very common type of ROS message for processing perception data in ROS. It is also one of the most complex messages to actually interpret. The complexity of the message derives from the fact that it holds arbitrary fields in a single giant data store. Web118 Read points from a L{sensor_msgs.PointCloud2} message. This function returns a list of namedtuples. 119 It operates on top of the read_points method.
