Rotative laser-scanning
Rotative laser scanning is a scanning method that use the red laser line embedded on the FABtotum head and the camera,
plus the 4th axis .
It takes two pictures of a rotating object: one with the line projected on the object to scan and one without. Then the post
processor installed on the Raspberry makes a subtraction between the two images, obtaining just the line modified on the
object’s profile. Many lines will compose the point cloud.
