An application of augmented reality focusing on the creation of 3D models using photogrammetry

Abstract

Nowadays, Augmented Reality (AR) is one of the biggest technology trends and it continues to grow, as smartphones and AR supporting devices become more accessible to the world. AR technology is used to superimpose digital content (images, sounds, 3D models, etc) onto the physical world. The creation of this content can be a complicated procedure, especially when building complex 3D models. In the first part of the current thesis, a 3D model construction technique called ¿photogrammetry¿ is presented. Using photogrammetry and Meshroom software, a 3D model of a replica is created. In the next part, AR is theoretically approached, followed by the presentation of the respective development tools. Finally, using the model created in part one and the aforementioned tools, two AR educational applications are developed: Application A, where using a mobile device, upon the detection of an image target, the 3D model is superimposed on the screen, and Application B, the stereoscopic version of Application A.
