3D white lights scanning, photogrammetric, reverse engineering.
Engineers in different areas of production increasingly using 3D scanning techniques, where speeding up the development process is one of the main factors for being competitive in today’s market. Virtualizations of the physical objects, to recreate parts where drawings or CAD data are missing, or to make the change to the existing one is one of the main use. From a wide range of commercial scanner used for digitalisation, 3D low-cost scanning system have gained a high interest. The aim of this paper is to show implementation of two low cost scanning system for creating digital replicas of mechanical part. The process of the digital data acquisitions, processing and creating 3D virtual model will be presented. A good implementation of light condition, sensor size/type of digital camera in the photogrammetric system can achieve high LOD (Level Of Detail) compared with structured light system. The displacement map generated from texture increase of the resolution geometry details as accurately as possible. Also for small parts the photogrammetry is more flexible or reliable.
