How do I find the distance between the moving objects?

[L_K]

I wrote a LabVIEW code for finding distance between 2 still objects. Now I what should I do if one of the objects is moving (all the time)? I just want to get an idea of how to analyze the moving picture. I have IMAQ vision builder 6.0, LabVIEW6i that comes with IMAQ tool, and IMAQ 1411 board. Do I need anything else beside those to analyze moving pictures?

You shouldn't need anything different since the moving picture is just that, a picture. The video is made up of multiple still frames so you will probably want to analyze frame continously to see the change in movement, or analyze several pictures and average the distance if you want the average distance. The code for capturing the continous frames will change (there are examples), but the analysis should not have to have significant changes made.
