Yesterday, Xilinx announced the reVISION stack for software-defined, embedded-vision apps. (See “Xilinx reVISION stack pushes machine learning for vision-guided applications all the way to the edge.”) Today, there’s a video demo of an application built with the reVISION stack and a second with more technical detail on optical flow. The first demo shows a working system that accepts video from two cameras, performs an optical flow transformation on one video stream, processes a recorded video stream from an SD card through a CNN, and then merges the video and optical-flow representations and outputs the resulting video on an HDMI screen. All of these operations occur within one Xilinx Zynq UltraScale+ ZU9EG MPSoC running on a Xilinx ZCU102 eval kit.


Here’s a block diagram of the demo showing how the three video streams are captured, processed, and displayed by the Zynq UltraScale+ MPSoC:

The two image sensors in this first demo are worthy of note. One is the new Sony IMX274LQC 4K60 image sensor designed for industrial applications. It’s connected to the ZCU102 eval kit over a MIPI interface running through one of the eval kit’s FMC connectors. The second camera is a Stereolabs ZED 2K stereo camera interfaced over USB 3.0, a high-speed native interface for the Zynq UltraScale+ MPSoC.


Here’s the 2-minute video of the operating demo:






For more details on the optical-flow part of the demo, here’s another 2-minute video:
