NOTE: This page documents the latest releases of PCL and pcl_ros. The Point Cloud Library (PCL) is a standalone, large scale, open project for 2D/3D image and point cloud processing. The range image is derived from the PointCloud class and its points have the members x,y,z and range. In addition to installing PCL, you will need to download and compile a set of 3rd party libraries that PCL requires in order to function. In this section, we will see some basic functionalities using the PCL library and its ROS interface. Ask Question Asked ... PointCloud2ConstPtr& cloud_msg) { // Container for original & filtered data pcl::PCLPointCloud2 cloud; // Convert to PCL data type pcl ... my problem was in the conversion from ROS message types to PCL point cloud types. Martin, What you are doing seems to be correct, but: * did you include the correct header file? PCL is released under the terms of the BSD license, and thus free for commercial and research use. We can handle the point cloud data from Kinect or the other 3D sensors for performing wide variety of tasks such as 3D object detection and recognition, obstacle avoidance, 3D modeling, and so on. Cheers, Radu. Introducing the Point Cloud Library. Turning a PointCloud into an Image Description: This tutorial is a simple guide to turning a dense point cloud into an image message Keywords: kinect, pcl, opencv, openni Tutorial Level: BEGINNER If you are using the ROS C Turtle release of PCL, see the C Turtle version of this page. These include ROS nodelets, nodes, and C++ interfaces. ROS … 33 * any way out of the use of this software, even if advised of the Point Cloud Library (PCL) runs on many operating systems, and prebuilt binaries are available for Linux, Windows, and Mac OS X. A point structure representing Euclidean xyz coordinates, and the RGB color.. Due to historical reasons (PCL was first developed as a ROS package), the RGB information is packed into an integer and casted to a float. The remaining code creates the range image from the point cloud with the given parameters and outputs some information on the terminal. It will make the handling of point cloud data much easier ,as you shall see. * do you have a correct pcl dependency in your manifest.xml? ROS PCL: Help with Moving Least Squares filter.

This package provides interfaces and tools for bridging a running ROS system to the Point Cloud Library. This is something we wish to remove in the near future, but in the meantime, the following code snippet should help you pack and unpack RGB colors in your PointXYZRGB structure: We will discuss the following examples:
