Pattern tracking

[muppy]

Hi All,

i need to track a pattern and calculate its centroid. I have Vision and IMAQ modules.

I'm totally new to LabView and i understad that this software has many capabilities and a lot of features.

Could you suggest me the features which i should learn in order to solve my task ?

Best regards,

Andrea

Hi Kudos,

thanks for suggesting me your code, but it is not working.

After loading the file, i get the error

"Error 1074396009 occured at IMAQ AVI open

Possible reason(s):

IMAQ vision: an internal DirectX error has occured. Try upgrading to the lastest version of DirecX"

I upgraded to the last version of DirectX, but this does not solve.

Best regards,

Andrea

Hi Andrea

Look at this thread for error solution http://forums.ni.com/t5/Machine-Vision/DirectX-Error-playing-AVI-file/td-p/1089274

Unfortunately the solution you suggested is not working for me. I continue to get the same error.

In any case, please note that i do not need to track an object in an AVI file, i need to track an object from a webcam

Could you suggest also a solution for this ?

Thanks,

Andrea

Hi Andrea,

here you can find a lot of NI Vision Development Module that you can use in order to realize your application.

I think they are very useful.

Hoping they will help you.

Best regards.

In this illustrative example, we will create a program in Labview capture an image pattern, after the search to show the location and coordinates, you can check the following article in the following link
