In this chapter, we have explored the different tools, algorithms, and interfaces that can be used to work with point clouds in ROS. The reader might have noticed that we have tried to link the examples together to provide more insight into how these kinds of nodes might be used in a reusable manner. In any case, given the computational price of point cloud processing, any kind of architectural design will be inextricably linked to the computational capabilities of the system at hand.
The data flow of our examples should start with all the data producers, which are pcl_create and pcl_read. It should continue to the data filters, which are pcl_filter and pcl_downsampling. After the filtering is performed, more complex information can be extracted through pcl_planar_segmentation,pcl_partitioning and pcl_matching. Finally, the data can be written to disk through pcl_write or visualized through pcl_visualize.
The main objective of this particular chapter was to provide clear and concise...
