Can we use this technique for point clouds as large as used in Construction sites? #2

Can we use this technique for point clouds as large as used in Construction site. Your method looks impressive so i wanted to try it for point clouds as large as in millions. Is it possible? Do let me know, and it there any email id i can contact you on? rizulv.jpr@gmail.com

Yes, it is absolutely possible to use the method on large point clouds. We tested it on indoor scenes with up to 10M points. The models actually process the data as spherical batches of up to 4096 points, allowing it to scale to very large point clouds.

However, the models are trained on data-specific noise. If you have paired data, e.g., professional laser scans of a site + a noisy scan (such as an iPhone LIDAR scan) of the same site, we recommend fine-tuning a model on the specific noise.

The data has to be aligned first (IPC or similar). You can look at our preprocessing script and Supplementary for more details.
