Good afternoon.
Actualy I'm working on a 2D motion tracking proyect. I'm new programming in Labview, first at all I have started downloading the IMAQ vision and acquisition to get video frames thanks to the Vision assistant but I'm not able to do it without it, I have tried to do it with the IMAQdx sequence with no succesful, I have tried to save the frames on an array but I only can get the last snap of the sequence. I have done a program to localize a black point on a .jpg file but I'm not able to match it with the video frames that I could get from the Vision assistant. So far this way, my questions are:
How can I match my localize black point program with the video frames with the vision assistant?
How can I get video frames without using the Vision assitant?
And if I going for the wrong way to do a 2D motion tracking... How can I start it? If there is some tutorial, references or something what I could use to guide me?
Thanks in advance.
PD.
I have upload the program where I locate a black point as a "locate black point" and the adquisition with the integrated program.

Not at all, I have done a program where I can follow a point but now, I need to track two points, In fact, two lights with black background but I tried it, it got confused with the two points.

Hi
Post any of your image. For motion tracking i done previously with video, see here

Using a sheet of paper, I drew a little black circule and with that I made the pattern to follow in real-time. Now I have to track the white points of the next AVI. video and set it in real time(some guy as it the video) to measure the position of the points (x,y positions) , but It seems that the programs confuses the patterns.

And I wasn't able to run the VI that you made for tracking. It says the "draw pattern matches position.vi: SubVI is missing".
AND Thanks for your time and help ![]()

Hi zero1581,
the sub vi i got from the bult in example. Open Pattern matching example in LabVIEW Example finder. so that you can fix this issue.
Regarding the avi you attached the video is not clear there are little noises added up while processing.

In fact, the point of this AVI is jus to follow just a few white points (three points: on the beginning of the leg, on the knee and on the beginning of the foot) I think I supposed to "Process" the AVI.
