FPGA Vision Help

[Gary117]

Hi all,

I have some questions I was hoping someone could help me with. I’m programming an FPGA Camera-Link card (NI PCIe-1473R). I have a decent amount of programming experience in Labview on a PC, but I’ve never interacted programmatically with other hardware so I’m a little lost.

I’m trying to make sense of the inputs from the camera to the card, but I don’t know how to interpret them. I’ve attached a file showing all of the FPGA I/Os for the specific card. There don’t appear to be any input terminals that are formatted as images, so I’m guessing the image comes in pixel by pixel formatted as numbers (i.e. 16 bits of color and 8 bits of x and y coordinates for each pixel in a given frame or something along that line). However, I don’t know which terminals correspond to what or how to put the signal together.

Any help or advice would be appreciated. Thanks!

Hi Gary,

My suggestion is to first work from the Vision RIO examples in the example finder.  All of the examples are commented and should at least help you get started.  Also, check out this tutorial on Digital Camera Basics, you will notice many of the concepts talked about here in the code itself.

You are correct in your assumption that the image comes in pixel by pixel and you can read more about the image's construction in the article and see that construction in the example codes.
