For the purpose of automatic 3D point cloud segmentation, labeling, and download, I am in the process of creating an open structure for online classification. For now, you can just send me your dataset as a .las file under 2 Go, named after you, to my mail address, create an account on flyvast.com (free), and I will share the project once the results are ready (10 million points per minute)
In a second time, I will create an independent structure for researchers and academia to label very easily any point cloud.
Example of unsupervised segmentation (real-time results here)
