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.

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.
