Access point cloud messages
The PointCloud2
object is an implementation of the
sensor_msgs/PointCloud2
message type in ROS. The object contains
meta-information about the message and the point cloud data. To access the actual data,
use readXYZ
to get the point coordinates and
readRGB
to get the color information, if
available.
ptcloud = rosmessage('sensor_msgs/PointCloud2')
creates an empty PointCloud2
object. To specify point
cloud data, use the ptcloud.Data
property. You can also
get point cloud data messages off the ROS network using rossubscriber
.
