What is a Point Cloud?


What is a point cloud?

Point clouds are mass amounts of data comprised of thousands of x, y, z coordinates that represent surfaces of objects in the real world. A point cloud is best understood by experiencing it or seeing with your own eyes, so we compiled some short footage of point clouds for you!





How to make a point cloud:

Point cloud coordinates are generated from reality capture methods like LiDAR and photogrammetry. LiDAR, also known as laser scanning, uses lasers to accurately measure distances of thousands of points and creates surfaces based off those data points. Photogrammetry is a more passive method that also uses light; the scanner does not emit the lasers/light itself. Instead, it takes pictures and stitches them together using math to generating 3D models. These 3D models can be turned into point cloud data as well.


Why do we use point clouds:

For Architecture, Engineering, and Construction we generally perform reality capture to document existing conditions. This documentation is used for as-builts for remodels, verifying construction progress, and historic preservation.
