Development of an Object Scanning System for Storing the High Definition 3D Data of the Planar and Non-Planar Surfaces

Abstract

Computer graphics technologies are significantly advanced. This results in the requirements for 3D models that are realistic in order to display on the screens of the electronic devices, in the movie, video game, animation, sculpture, architecture, product design, augmented reality (ar), and virtual reality (vr) technologies industries as well as to print the 3D models through 3D printers. The purpose of this research study is to design and develop the object scanning system for storing the high definition 3D data of the planar and non-planar surfaces by taking the photos of real objects in many angles with the DSLR digital camera to store high definition photos. The colors of the photos of the objects were adjusted with the color calibration method from the color checker with 24 colors. To take photos, the photos of the objects were divided into two main parts. For the first part, the studio camera with white LED was used for taking 360 degree photos being processed with photogrammetry in order to create 3D models and texture maps of the objects. For the second part, a 3D scanner was used in order to scan the surfaces of the objects at the same angle with the different directions of lights from eight light bulbs in order to process the photos with photometric stereo for creating base color maps, normal maps and heightmaps. Finally, the map photos were inputted in the 3D models. Then, the 3D models were rendered. As a result, the 3D models had high reliefs, bas reliefs, rugged surfaces, deep grooves and patterns. Additionally, the colors on the surfaces were consistent with the real objects.
