Draw/represent trajectory with IMAQ Overlay Points VI

[Bender83]

Hello everyone,
I'm working on a project of visual tracking, in which with mouse I create the region of interest (ROI) of the onject and then I start to tracking the object. I need to draw/represent the trajectory of the cross of the region of interest of the object as shown in figure attached. I'm working with IMAQ Overlay Points VI but I'm certainly leaving out some details and I hope for your help.
Thank you.

Hi,

could you please explain your problem and your goal better?

If the issue is that you are simply drawing one single point and not a trajectory, you could build an array of the points you are locating each iteration and passing this array to "Array of Points" input either of IMAQ Overlay Points.vi or of IMAQ Overlay Multiple Lines.vi.

I hope this helps!

Bye!

Thanks for the answer, I will be more clear.

I would like to represent the trajectory formed by the points that coincide with the cross of the region of interest (ROI) during the tracking composed by a number of points that I can establish arbitrarily in the VI.

Thanks a lot.
