Image-based three dimensional (3D) scanning is a photogrammetry method.
Photogrammetry is a scientific discipline used for obtaining dimensional
information from photographs taken of objects. This discipline used in the
mapping of geographical areas with photographs taken from airplanes at first,
began to be used in obtaining the 3D model of objects with the development of
the technology. Image-based 3D scanning method which is becoming increasingly
widespread in the field of photogrammetry has become important like laser and
optical scanning methods in areas of reverse engineering, personalized design,
forensics, biomedical, industrial design, virtual reality. This method has some
advantages such as low cost, color modeling compared to other 3D scanning
methods, and yet is questioned in some aspects such as dimensional accuracy and
surface integrity. In this study, as a result of the scanning operations on small
size (125-1000 cm3) objects, the digitized models and the actual objects were
compared dimensionally. In addition, glossy, transparent and matte surface
objects were modeled by image-based 3D scanning method and the differences
related to the process were revealed and the precautions to be taken were
stated. This article is thought to be useful for researchers who want to use
image-based 3D scanning in their study.
