Science
A structured pattern (dots, square markers, parallel lines…) is projected onto an object to be measured.  The curved surface causes the pattern to deform (the straight lines turn into curved lines…).  The way and amount of deformation to the original uniformed structured pattern is purely due to the surface shape.  In other words, the surface shape information is encoded into the deformed structured pattern.   A sophisticated computer program is involved to “decode” the surface shape — to turn each pixel of the deformed pattern image into a spatial point with known XYZ coordinates.  The collection of all these XYZ points (could be easily over 300,000+ ), which represents the 3D shape of the object, is called “point cloud” data.
