Re: Virtual Birds-Eye View?

I actually messed around with this at work, trying to get it ported to a FRC environment.

I was using a Qualcomm snapdragon reference board (disclaimer, I work there and happened to have one on my desk). The main reason why I used that was to easily perform the matrix transformations to unwarp and change perspectives on 4 images.

I attempted to throw the same code on the roborio since our team was limited by constraints and didn't have room/space/weight for additional hardware to support the board.

We quickly ran into a USB bandwidth issue and decided not to pursue it further. It was a fun exercise and a good introduction into linear algebra and some calculus for our kids.

If you want to give it a whirl, I highly recommend looking at this white paper. http://delphi.com/docs/default-sourc...f.pdf?sfvrsn=0

Fun fact: We also got it working just by using WebGL with some javascript to pull in 4 images. That's one way to take advantage of a high performance GPU found in your laptop!
