All,

We have added a few more updates to our performance analysis. So far based on our testing the Tegra TK1 is capable of processing 640x480 images well over 30 frames per second without any lag, just using OpenCV on the CPU. There is a lot of CPU headroom left.

We need to perform additional tests on the RoboRio. I remember one test where we were able to run 320x240 at 30 frames per second without any noticeable lag with x11 forwarding enabled, but the data for other frame rates do not support that conclusion. We are double backing here and re-running our testing to ensure accuracy. We also need to make sure that all cores are being used on the Rio.

We can safely conclude however, at the moment that under our test conditions, the RoboRio can not process 640x480 images at 10fps or higher without experiencing noticeable lag. We are still trying to determine at what framerate we can achieve lag free 640x480 processing on the RoboRio. Our baseline test suggests 8fps but we have not run any performance test to confirm.

We still have yet to post any processing results from the BeagleBone black, so look for those soon.

The URL where we are documenting these tests is here: http://khengineering.github.io/RoboR...on/cameratest/

If you have any questions about our test methods, or conclusions, please let me know.
