3D CPS applies a measuring technique based on the laser triangulation system. The measurement system is made up of a camera and a laser source, both properly calibrated. From the operational point of view, a light plane is projected on the scene and an image of the light line is acquired, representing the intersection between the laser plane and the items present in the scene: this line is referred to as profile, while the measurement system is known as profilometer.
The analysis proceeds then focusing attention on the profile only leaving aside the rest of the image, thus choosing not to measure the part of the scene outside the profile and going back to a two-dimensional measure. The information on the third dimension allowing the three-dimensional reconstruction is obtained moving the profilometer, thus acquiring different profiles of the same measurand.
