Labview and OpenCV

[jcmb]

Hello,
I'm having troubles in linking Labview with an OpenCV dll. Does anybody know the best way to do it? Is there any wrapper for OpenCV (some C code that could be used in a CIN block)  to ease link with Labview? The question is a matter of data types that do not match...

Thank you for your attention

Hi
Can  you precise the question?
Are you using this dll to control  a camera? The question is it to call a dll in LV?

Hello,
I want to use the Optical Flow implementation of OpenCV libraries in Labview. To do so I'm using the Call Library Function Node of Labview. The problem is that the OpenCV function uses, as input arguments, a data type called CvMat that does not look like the regular data types (like "arrays", for example). What I'm asking is if anybody has already developed some Labview  vi to "create" this datatype (what is usualy called "wrapper") to make it possible to link Labview to OpenCV.

Hope I've been clear...

Thank you for your time.

Hi
I have never used this library unfortunately.
But don't  you have an help file about the parameters you have to pass to the function?
I suppose that this type is also like a structure?

Bonjour,

on a un problème concernant l'exploitation de données sur labview à partir d'un tableau construit sur exell.

En effet le tableau comprend 2 colonnes correspondant à un courant et à un temps.Le problème c'est de faire passer ces données sur labview afin de pouvoir les exploiter ligne par ligne.

si vous avez des exemples de code permettantde réaliser cela,ils serontles bienvenus.

Merci d'avance.
