The first step in reverse engineering a physical part is to gather 3D surface data points. This is typically accomplished using a Coordinate Measuring Machine (CMM). However, as most CMM's use a Cartesian reference frame, often large parts of an objects surface cannot be measured. A novel system was developed to collect 3D surface data using a cylindrical/prismatic device. A 3D laser-scanning device obtains surface information by emitting a structured laser line which, when reflected by the object being scanned is received by a CCD camera. In this work a stripe-type laser is used so that many points can be acquired at once.
