Multiple Pattern Matching IMAQ

[agentj4y]

Hello, 

I'm trying to create a program that allows the user to draw an axis and a function on paper, and then finds the best fit function.  I'm having difficulty with the pattern matching because I'm trying to learn in a bunch of different axis so that it will always recognize, but I cannot seem to get the matching to work for the axis to start.  I don't really know how to fix it.  The program is included.  Any assistance would be appreciated.

Thanks

Hi agentj4y,

Can you please post for lv12.

What u want to match co-ordinate axis which will be drawn by user or something else?

If you have different size of images may be geometric matching will be good choice but its time consuming though.

By looking at the  images which you have provided, I was able to detect both of them in geometric but not in pattern matching.

For more on geometric matching please check http://zone.ni.com/reference/en-XX/help/372916L-01/nivisionconcepts/geometric_matching_technique/

The coordinate axis will be drawn by the user, along with some other stuff. so it needs to be able to decipher how many people could do the coordinate axis.

Also, does my system work because I keep getting "Invalid geometric matching template image" error on the learn template feature.
Thanks
