What is a Point Cloud?

Point Cloud

3D Machine Vision captures an object’s location and shape in a format suitable for processing by a computer or a PAC/PLC.  An object’s surface is represented by a list of three-dimensional coordinates (X, Y, Z), referred to as a “Point Cloud.”

Shown is the process of Hermary’s 3D scanner capturing the point cloud data of an orange. Individual scans (or profiles) can be seen as lines of points.  Combining the profiles in the Z-axis renders a 3D representation of the shape of the orange. Point Cloud data from multiple scanners can be “stitched” together to see all around an object or when scanning larger objects. Stitching point cloud data is sometimes referred to as coordinate remapping.
