Abstract
Complying with security certifications in most harsh industrial areas is usually very expensive and sometimes hinders the industrialization of new technologies. Thus, we observe in the modern industry an increasing need for visual inspection and closed monitoring systems, either manual (direct and permanent observation of a supervisor) or automatic (usually through Computer Vision applications) to monitor hazardous environments. In such conditions, the use of incoherent optical fiber bundle (IOFB) for image transmission is probably the most appropriate solution. This option requires a prior calibration step to perform the reconstruction of the IOFB output image, where the reconstruction process is very efficient, according to the latest studies. It is of further interest to introduce and extend this technique in industrial applications, to make possible the portability of IOFB calibration. Indeed, a slight position shift of the system may corrupt the calibrated IOFB, consequently invalidating it for image transmission. We propose a new method to quickly and automatically solve this problem. Such an image acquisition and transmission system is very attractive for commercial introduction, since the IOFB can be pre-calibrated, and the calibration quickly recomputed any time it is needed without loss in image quality. The presented work has been submitted for patent.
