Real life augmented reality for maintenance

A major challenge for Augmented Reality (AR) in real life maintenance is varying lighting conditions. This research developed a novel registration technique to use AR effectively in real life lighting conditions, where registration is the accurate alignment of real and virtual images. The study has demonstrated that the registration technique can register shiny samples and implements image enhancements on dim samples within a Non-Destructive Testing environment. The experimental set-up included recognition efficiency testing on shiny and dim samples. A detailed aerospace maintenance case study has been used to validate the registration technique. The results show the duration of registration reduced and the accuracy improved for both shiny and dim samples.
