Abstract: Using Augmented Reality for Nondestructive Testing [DE]
Robert Deppe, Using Augmented Reality for Nondestructive Testing, Hochschule Düsseldorf, Bachelor thesis, 29.5.2018.
The aim of this thesis is to describe the application of augmented reality technology in non–destructive testing of products of the metal–industry and to create a prototype. This prototype is created with hard– and software, that is usually employed in the gaming industry, and delivers positions for creating c–scans. Using the ZEDmini in combination with the HTC VIVE enables realtime visualisation of the probes path in the HMD, as well as the setting of virtual markers on the specimen. As a part of the implementation the downhill–simplex optimization algorithm is implemented to fit the specimen to a cloud of recorded surface points. The accuracy is statistically tested and evaluated with the result, that the VIVE–trackingsystem is accurate up to ca. 1–2 millimeters in well lit conditions. This thesis is of interest not only for research–institutes of the metal–industry, but also for any areas of work, in which the enhancement with augmented–reality is possible.
