Abstract

The automotive industry increasingly uses close range photogrammetry systems with bundle adjustment for acquiring 3D information to check for example the quality of sheet metal parts. Because of its flexibility, at times a photogrammetric system is used in climate chambers and hence is exposed to extreme strain. The interior orientation of the camera whilst capturing in the difficult environment can not be assumed to be stable and an appearance of wear may occur over time. This paper presents the effect of unstable lens fixings. A practical adaptation for reducing the lens movement, whereby the commonly used ring flash is dissociated from the lens, is introduced and successfully tested. Also, a mathematical model to compensate the effect of lens inclination is presented and verified by the German guideline VDI/VDE 2634 Part 1. First results show significant improvement in maximum length variation, which is the desired parameter in the guideline VDI/VDE 2634 part 1.
