Velodyne LiDARSensors Data Acquisition

Acquire point clouds from Velodyne LiDAR sensors

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

Functions

`velodynelidar`	Create`velodynelidar`object to acquire point clouds fromVelodyne LiDARsensor
`preview`	Preview of live point cloud data fromVelodyne LiDARsensor
`closePreview`	Close preview of live point cloud data fromVelodyne LiDARsensor
`start`	Start streaming point clouds fromVelodyne LiDARsensor
`flush`	Delete point clouds in`velodynelidar`object buffer
`read`	Acquire point clouds from`velodynelidar`object buffer
`stop`	Stop streaming point clouds fromVelodyne LiDARsensor

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 thereadcommand.
Read and Compare Two Point Clouds from a LiDAR Sensor
This example shows how to acquire the oldest and newest point clouds from the buffer and display them to compare the images.

Log and Visualize 3D Data from Velodyne LiDAR Sensor

Acquire lidar data from a Velodyne LiDAR sensor device. A lidar sensor creates a 3D 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 3D mapping, surveying, industrial automation, and autonomous vehicle navigation.
