Point Cloud Library vs RIEGL RiSCAN PRO

Point Cloud Library (PCL) is a free, open-source project for processing 2D and 3D images and point clouds. Its algorithms cover filtering, feature estimation, surface reconstruction, registration, model fitting, and segmentation. They can be used to reduce noise, join point clouds, divide scenes into segments, find keypoints, calculate descriptors, create surfaces, and visualize point data.

PCL is divided into smaller code libraries that can be compiled separately, supporting distribution on systems with limited computing capacity or storage. Prebuilt binaries are available for Linux, Windows, and macOS, and the project recommends package managers to distribute PCL and simplify installation of its third-party dependencies. It supports OpenNI 3D interfaces for acquiring and processing data from devices such as PrimeSensor cameras, Microsoft Kinect, and Asus XTionPro. The API reference includes public methods and classes, code snippets, and links to scientific publications. PCL uses the 3-clause BSD license and is free for commercial and research use.

RIEGL RiSCAN PRO is operating and processing software for terrestrial laser scanning projects on Windows 11. It supports data acquisition, visualization, and processing for RIEGL VZ-Line and VZ-i series scanners, with real-time field streaming and automated batch processing. Point-cloud tools cover automatic registration, multi-station adjustment, filtering, merging, colorization, meshing, and volume calculation, plus volume measurement. Data from multiple sensors, including external cameras, can be combined into colorized point clouds with added attributes. Projects can be exported in formats including .e57, .las, .laz, .obj, .stl, .dxf, .csv, .pts, and .ptx. A documented XML project structure supports transfer to third-party post-processing software. Plugins include RiPANO, LIS GeoTec, LIS TreeAnalyzer, and an AI anonymizer for faces and license plates. Listed applications include façade measurement, as-built surveying, forestry, topography, archaeology, and city modeling. Pricing is on request, and downloads are restricted to RIEGL customers.
