One of the challenges for railway safety is in the complex railyard environments. Railyard workers in a noisy environment are often surrounded by dangerous moving objects and can easily result in accidents or casualties. Thus, monitoring the railyard workspace to keep personnel safe is particularly challenging.

Dr. Hamid Sharif and his research team in the University of Nebraska-Lincolnused Ancortek SDR-KIT580AD to improve railyard safety. They used visual images to monitor a wide areaand used Ancortek SDR-KIT 580AD to address the low-visibility problem within100 m workspace. They successfully maintained real-time processing withless than0.1 s consecutive frame time.
