Hmm, it appears I have spoken too soon.
I was going to do a latency measurement similar to how Greg Mckaskle did it a while back (using the LEDs on the cRIO).
However, I'm having trouble getting the cRIO to create a TCP connection with the camera.
The camera
does work on my computer. (As far as I can tell, you can only capture jpegs, not cgi images, so it does require slight modification to the camera software. What I've done is just use the "get image" inline in my code, instead of having it asynchronous.
Of course, I'm not one to just send the image back to the driver station.)
So, i'll get a latency measurement once I get it working. Sorry about that.
EDIT:
I got it working now. There were just some troubles with IP address.
The latency is around 400ms on a small image image (175 x 144), 500ms on medium (320 x 240), and 550ms on large (640 x 480). These values may vary by at least 100ms each way. It's a cheap camera.
Here's a screenshot of the latency test:
(When the case is FALSE, it just passes the data through)
