| Summary: | This work presents an approach for the task of person re-identification by exploiting bifocal stereo cameras. Present monocular person
re-identification approaches show a decreasing working distance, when increasing the image resolution to obtain a higher reidentification
performance. We propose a novel 3D multipath bifocal approach, containing a rectilinear lens with larger focal length
for long range distances and a fish eye lens of a smaller focal length for the near range. The person re-identification performance
is at least on par with 2D re-identification approaches but the working distance of the approach is increased and on average 10%
more re-identification performance can be achieved in the overlapping field of view compared to a single camera. In addition, the 3D
information is exploited from the overlapping field of view to solve potential 2D ambiguities. |
