Abstract

The aim of this work is to investigate the performance of 3D-scanning using a laser-plane of light sensor combined with a turntable. To this end a complete measurement system was designed, implemented and tested. A new calibration concept was conceived and the required calibration objects and procedures were implemented. There are two main steps involved: calibration of the plane of light measurement unit; and registration of the axis of rotation relative to the laser plane of light. The complete system, optical measurement, rotation control and surface reconstruction has been implemented and successfully tested on a series of engineering objects. The acquired data can also be exported to a CAD an STL data file.
