摘要：This paper explains the 3D scanning procedure of creating a virtual 3D model from photographs by using a process called photogrammetry. It starts by giving a technical explanation of different technologies for 3D scanning, explains why photogrammetry was chosen and gives general specifications of hardware and software used in the process. The whole procedure is then thoroughly shown step by step on a physical object,and in the end an analysis of the generated 3D model and its variations is given.
