Structured light scanners use ultra-high accuracy/resolution optical imaging to triangulate points from multiple locations. By comparing millions of pixels, this process can produce a more precise point cloud with a better definition of subtle edge features.

3D Laser Scanning is a non-contact, non-destructive technology that digitally captures the shape of physical objects using a line of laser light. 3D laser scanners create “point clouds” of data from the surface of an object.

Photogrammetry is the science of making a measurement from photographs! It seems pretty simple, no? This method uses the parallax obtained between several pictures, taken from different points of view.
