When you launch MeshLab, there's usually no LiDAR scan loaded. e57 file.įor this article, the terms mesh, point cloud, data set refer to the same thing: the collection of vertices produced by a LiDAR scan. The Pantheon scan is attributed to Gerd Graßhoff, Michael Heinzelmann, Markus Wäfler, Christian Berndt, Jon Albers, Oskar Kaelin, Bernd Kulawik, Ralph Rosenbauer, Nikolaos Theocharis, Michael Lustenberger, Bernhard Fritsch in 2021, and is distributed by Open Heritage 3D under the CC BY-NC-SA license.Īfter downloading the mesh file, unzip it to uncompress the. If you just want to browse through a scan, the Pantheon (10.26301/t9sj-mf53) dataset is surprisingly clean and is only 89 MB with just 6 million vertices. To work on a LiDAR scan comfortably, anticipate requiring a good graphics card and plenty of RAM. LiDAR scans contain millions of points that define an object, so they're very taxing on system resources. The project has scans of ancient ruins at Tikal cathedrals in France, Spain, and Italy palaces in Syria and Jordan and more, published under the terms of Creative Commons licenses. However, the OpenHeritage project is dedicated to archiving scans of significant scientific and public interest. LiDAR equipment isn't easy to obtain, so unless you're working on a project using LiDAR scan, you probably don't have a LiDAR scan just lying around.
