Smartphone-based photogrammetry assessment in industrial engineering

This paper presents an innovative way to assess smartphone-based photogrammetry's precision in an industrial environment using 3D printed gauges. The proposed methodology is based on 3D printing technology to create the gauges, which were modeled using CAD software. The resulted gauges were measured using a CMM to obtain the real nominal value, and are compared with the resulted photogrammetry models in order to assess their precision. In the case study only angles were measured, because these are not affected by scaling, thus the errors during measurements are considerably reduced.
