How does the Pine A compare with the Raspberry Pi in terms of vision processing?  I tried a simple OpenCV blob tracking example with the Pi, and it gave an unacceptable framerate of 5-7 FPS.  Can we expect a better framerate with the Pine (20-30 FPS)?

Note, in reading the datasheet for the pine64 camera (https://drive.google.com/file/d/0B0cEs0l...yUWYw/view), I discovered that the camera can only do about 15 fps at full resolution.  If you don't need full resolution, then it get a higher frame rate (720p at 30fps and VGA at 60fps).  Note, this is just for the camera itself, and not any bottlenecks due to communication or processing.

Ewww. Sad
Come on! And that's on a parallel line too. 
It's like putting a Fiero engine in a Ferrari (smh).
Not ideal. I'll have to send an email to these guys.

To be fair, this is what the rpi can do on the older hardware (not pi3):
  • 2592×1944 1-15fps, video or stills mode, Full sensor full FOV, default stills capture

  • 1920×1080 1-30fps, video mode, 1080p30 cropped

  • 1296×972 1-42fps, video mode, 4:3 aspect binned full FOV. Used for stills preview in raspistill.

  • 1296×730 1-49fps, video mode, 16:9 aspect , binned, full FOV (width), used for 720p

  • 640×480 42.1-60fps, video mode, up to VGAp60 binned

  • 640×480 60.1-90fps, video mode, up to VGAp90 binned

But the camera is more expensive (like 20 bucks).
