| description | This study describes a cost-effective check-in baggage screening system, based on "on-belt tomosynthesis" (ObT) and close-range
photogrammetry, that is designed to address the limitations of the most common system used, conventional projection radiography.
The latter's limitations can lead to loss of information and an increase in baggage handling time, as baggage is manually searched or
screened with more advanced systems. This project proposes a system that overcomes such limitations creating a cost-effective
automated pseudo-3D imaging system, by combining x-ray and optical imaging to form digital tomograms. Tomographic
reconstruction requires a knowledge of the change in geometry between multiple x-ray views of a common object. This is uniquely
achieved using a close range photogrammetric system based on a small network of web-cameras. This paper presents the recent
developments of the ObT system and describes recent findings of the photogrammetric system implementation. Based on these
positive results, future work on the advancement of the ObT system as a cost-effective pseudo-3D imaging of hold baggage for
airport security is proposed. |
