Digitization of the Virtual Reality Laboratory Through Photogrammetry Tools (SfM)

Abstract

The present paper focuses on generating a digital laboratory model at the department by applying the structure from motion technique. The generated digital model is then utilized to create simulation models for application in virtual and augmented reality environments. Nine different approaches to photogrammetric imaging in the laboratory were tested in the experiment. These approaches involved variations in the number of photographs and scanning positions. The results of the experiment were divided into three categories: unsuitable, which required significant modification; incomplete, which required further modification; and suitable, which was directly usable. Some images were unusable due to the similarity of objects in the scene. Experiments showed that some parts of the laboratory were more appropriate to image separately. It was also found that dark and shiny surfaces of objects presented a problem for the computation of the models. Therefore, it was necessary to use markers or colours to eliminate this problem.
