Recently the Zebracorns (FRC Team 900) from Durham, North Carolina participated in the 2015 FIRST Robotics competition. The event was held in St. Louis in April. As part of their robot, they integrated a NVIDIA Jetson TK1 connected to a Logitech C920 camera. They used the Jetson to run Zebravision 3.0 which is a library and several applications used to detect recycling bins in the 2015 FRC game.
The Zebravision library detects objects using the OpenCV cascade classification functions and local binary patterns facilities. The students wrote a white paper about the Zebravision library, which is available from the Chief Delphi website at: http://www.chiefdelphi.com/media/papers/3147?
They have also made their code available on the Zebracorn Github account: https://github.com/FRC900/2015VisionCode.
The whitepaper gives a good background on how they trained their cascade classifier, and how they approached building the overall system. There’s also a hint of things to come.
Impressive work from the young roboticists.
