Online Recognition Using NI VDM and ADLINK Grabber

[saifizi]

Dear All,

Now, I make some program using NI VDM and ADNLINK Grabber. I want to program online recognition using pattern matching method. I can read image program the grabber using Labview 8.6, but when I want to learn image and search image the program can't do it. some massenge that I get from labview. I attach the program that I done. Error that I found is;

a. occured at IMAQ learn pattern 2- the template is too smaall. IMAQ Vision: (Hx 0xBFF6079E) the template is too small.

b. Occured at IMAQ Match Pattern 2 Invalid template descriptor. Imaq Vision: (Hex 0xBFF60791) invalid template descriptor.

 I hope some one can help me. Thank you very much.

The template is too small. Cannot be created because not enough learn information. Try to select bigger ROI. The next error invalid template descriptor - template is invalid because was not created, because too small.

In additional, as far as I know, Learn Pattern accepts 8 bit gray images only (but not sure - check help for supported image types).

For real help:

a) post VI without missing SubVI (grabber related)

b) post images and show desired ROI.

Andrey.
