Abstract:
In this paper, we present a hardware unit for real time component labelling with Centre of Gravity calculation. The main targeted application area is light spots, used as references for robotic navigation. Centre of Gravity calculation can be done in parallel with a single pass component labelling unit without first having to resolve merged labels. We present a hardware architecture suitable for implementation of this Centre of Gravity unit on Field Programmable Gate Arrays. As a result, we get high frame speed, low in power and low in latency design. The device utilization and estimated power dissipation are reported for the Xilinx Virtex II pro device simulated at 86, Video Graphics Adaptor (VGA), sized frames per second. Maximum speed is 410 frames per second at 126 MHz clock.
