how do I trace the moving object using Imaq

[Burt_S]

Hello, I have attached a basic example of how to find the center of a circle.  This was modified from the particle analysis example in the example finder.  This should be a good starting point for you. You should be able to use the center point of this circle to get the remaining information that you need.

Hi Burt S,

Thanks for your support.

I only have lv7.1 with vision 7.1.

I can't open your lv8.6 program.

Can you post the script picture or using 7.1 example?

Thanks.

Robert

Hello Robert,

Unfortunately I am unable to post my example in a format compatible with LabVIEW 7.1.  What I would recommend would be to take a look in your examples for LabVIEW 7.1.  You should see an example called 'Particle Analysis Example' which is located in the LabVIEW 7.1\examples\Vision\2. Functions folder. 

This VI example will walk you through thresholding an image, filtering out the smaller particles, and finding the center of mass of all particles remaining.  It should only require some tweaking of the thresholding, as well as in the last frame where it calculates its statistics, for you to be able to find the coordinates for the center of the circle.  You can then build off of this to create your remaining functionality.
