Comparison of Free Android Mobile 3D Modeling Tools for AR Apps

Abstract:

User expectations regarding the functionality of mobile devices have led to the development of applications with digital representations very close to reality that require the least amount of resources. Until recently, three-dimensional modeling required the compulsory participation of an expert in the field, increasing two valuable resources: time and money. Augmented reality offers the possibility of recreating reality on your smartphones through 3D objects. Currently there are applications that generate three-dimensional objects using photogrammetry. The objective of this work was to compare free Android mobile applications, to identify one that generates a good enough result to be used in augmented reality. The investigation corresponds to the quantitative model with experimental design, the tests were carried out in: 3D Escáner Live, 3DScanLink and Qlone; the results were tested on a prototype AR app. For the analysis, the quantitative evaluation methodology of textured models was used with the metrics: density, in which the 3D Escáner Live app generated a higher value in two of its three objects, with an equivalent to 66.67%; as well as in the difference of forms and comparison of contours where it obtained the highest percentage with 90.23%; and in the variation of the curvature in which it reached an average of 62.61% similarity in contours and edges; while in the number of textures over the number of visible points, all the applications obtained 100%. In conclusion, 3D Escáner Live is the one that generates a 3D model of better quality.
