ROS Specialized Messages

Access messages from specialized sensors and inputs

Specialized message functions enable you to create and access sensors and data types using specific ROS message types. For examples of accessing data from these sensors, see Work with Specialized ROS Messages.

Objects

`CompressedImage`	Create compressed image message
`Image`	Create image message
`LaserScan`	Create laser scan message
`OccupancyGrid`	Create occupancy grid message
`PointCloud2`	Access point cloud messages

Functions

`writeImage`	Write MATLAB image to ROS image message

Laser Scans

`readCartesian`	Read laser scan ranges in Cartesian coordinates
`readScanAngles`	Return scan angles for laser scan range readings
`plot`	Display laser or lidar scan readings

Point Clouds

`readXYZ`	Extract XYZ coordinates from point cloud data
