  This paper presents a localization system that uses infrared beacons and a
camera equipped with an optical band-pass filter. Our system can reliably
detect and identify individual beacons at 100m distance regardless of lighting
conditions. We describe the camera and beacon design as well as the image
processing pipeline in detail. In our experiments, we investigate and
demonstrate the ability of the system to recognize our beacons in both daytime
and nighttime conditions. High precision localization is a key enabler for
automated vehicles but remains unsolved, despite strong recent improvements.
Our low-cost, infrastructure-based approach helps solve the localization
problem. All datasets are made available.
