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.

- Get Started with Velodyne LiDAR Sensor Acquisition
Get started with Velodyne LiDAR sensor acquisition.
- Create a velodynelidar Object and Use Object Properties
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. - 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.
