A Framework for Using Photogrammetry in 3D Scanning

Abstract

The paper presents the necessary steps to be completed in order to obtain a 3D model through photogrammetry as an alternative to 3D scan. The methodology described in the paper does not aim to present photogrammetry as a substitute for 3D scan but as a low-cost alternative and/or for occasional use. The framework presented is highlighted by tests performed on an object that has most of the "disadvantages" for the photogrammetry operation. The results are analysed from a technical point of view and correlated to the duration of each stage. This analysis is performed in order to underline the methods and means of improvement. At the same time, the paper presents a structured approach in order to obtain a working 3D model that could be further improved in any CAD software.
