Thank you for the answer. The problem is I can't install pcl for ROS. I hva eproperly install pcl 1.7 on ubuntu but it seems there is no pcl install on my ROS kinetic. I made a ros kinetic full install and pcl is not there. How can I add it to my ros kinetic? --- [Visit Topic](https://discourse.ros.org/t/normal-of-pointcloud2/3314/3) or reply to this email to respond.
