Laser Triangulation 3D Scanners
A laser triangulation 3D scanner uses a laser to project a line and a camera to capture the line as it projects onto the surface of an object. As the object's shape and contours bends the laser line the camera detects the change and generates 3D data. Usually the laser and camera remain fixed while the object travels past the laser line and camera field of view.
