Data Acquisition with Velodyne LiDAR Sensors

Acquire point clouds from Velodyne LiDAR sensors

You access the point cloud data using the velodynelidar object. You can preview and read point clouds from the supported Velodyne LiDAR^® sensors.

Functions

`velodynelidar`	Stream point clouds from Velodyne LiDAR lidar sensor (Since R2020b)
`preview`	Preview of live point cloud data from Velodyne LiDAR sensor (Since R2020b)
`closePreview`	Close preview of live point cloud data from Velodyne LiDAR sensor (Since R2020b)
`start`	Start streaming point clouds from Velodyne LiDAR sensor (Since R2020b)
`flush`	Delete point clouds in `velodynelidar` object buffer (Since R2020b)
`read`	Acquire point clouds from `velodynelidar` object buffer (Since R2020b)
`stop`	Stop streaming point clouds from Velodyne LiDAR sensor (Since R2020b)

You access the point cloud data using the velodynelidar object.
Read Point Clouds
You can read all available point clouds or read a subset that you select. You can specify number of point clouds to read and specify them as the latest or the oldest point clouds in the buffer using arguments of the read command.

Log and Visualize 3-D Data from Velodyne LiDAR Sensor

Acquire lidar data from a Velodyne LiDAR® sensor device. A lidar sensor creates a 3-D map of the surrounding environment by using scanning laser beams and time of flight distance measurements. Lidar systems are used in a variety of application areas, such as a 3-D mapping, surveying, industrial automation, and autonomous vehicle navigation.
