In this tutorial we will learn how to do a simple plane segmentation of a set of points, that is to find all the points within a point cloud that support a plane model. Due to the dynamic nature of point clouds, we prefer to read them as binary blobs, and then convert to the actual representation that we want to use. The system can be configured to provide both 3D point clouds as well as radial velocity and reflectivity data for each point. You can use later that laserscan as a lidar for robot navigation. The size of the image is stored in the Width and Height properties.
