However you can not scan by hand, but you will need a precisely repeatable laser motion, e.g. by using a linear or rotating laser drive or by projecting a moving thin line by a video projector. Advantages You can scan objects that cannot be put in front of calibration planes, like very large objects or objects that are mounted on a wall. You can place the camera closer to the object because there need to be no background planes visible in the camera image. Systm - Episode 73 - Build a 3D Scanner From for $25.
