It is an open-source template library for linear algebra (matrices, vectors). Eigen ( ) is required at least in version 3.0.0.This set of C++ libraries is used for threading and mainly for shared pointers, so there is no need to re-copy data that is already in the system. The PCL library is built with the CMake build system ( ) at least in version 3.5.0. Some libraries are optional and extend PCL with additional features. PCL requires for its installation several third-party libraries, which are listed below. point cloud streaming to mobile devices with real-time visualization.cluster recognition and 6DOF pose estimation.aligning a previously captured model of an object to some newly captured data.recognize 3D objects on their geometric appearance.Point cloud library is widely used in many different fields, here are some examples: Ī large number of examples and tutorials are available on the PCL website, either as C++ source files or as tutorials with a detailed description and explanation of the individual steps. One was the extension of PCL for use with Python using Pybind11. For example, PCL participated in the Google Summer of Code 2020 initiative with three projects. The library is constantly updated and expanded, and its use in various industries is constantly growing. The library is fully integrated with the Robot Operating System (ROS) and provides support for OpenMP and Intel Threading Building Blocks (TBB) libraries for multi-core parallelism. PCL is cross-platform software that runs on the most commonly used operating systems: Linux, Windows, macOS and Android. Additional libraries such as Qhull, OpenNI, or Qt are optional and extend PCL with additional features. Boost is used for shared pointers and the FLANN library for quick k-nearest neighbor search. The visualization module for 3D point clouds is based on VTK. Most mathematical operations are implemented using the Eigen library. PCL requires several third-party libraries to function, which must be installed. These algorithms have been used, for example, for perception in robotics to filter outliers from noisy data, stitch 3D point clouds together, segment relevant parts of a scene, extract keypoints and compute descriptors to recognize objects in the world based on their geometric appearance, and create surfaces from point clouds and visualize them. It is written in C++ and released under the BSD license. ![]() PCL has its own data format for storing point clouds - PCD (Point Cloud Data), but also allows datasets to be loaded and saved in many other formats. Each module is implemented as a smaller library that can be compiled separately (for example, libpcl_filters, libpcl_features, libpcl_surface. The library contains algorithms for filtering, feature estimation, surface reconstruction, 3D registration, model fitting, object recognition, and segmentation. The Point Cloud Library ( PCL) is an open-source library of algorithms for point cloud processing tasks and 3D geometry processing, such as occur in three-dimensional computer vision.
