match pattern 4

[LOC91]

Hi William1225

I have a question. I run example in labview 2013 in help/find examples/toolkit and modules/ vision/calibration/simple calibration.VI. 

in example, use IMAQ read calibration and info.VI. I use IMAQ get calibration and info 3 to indicate error statistics parameter. But I get zero values. I think the result will different zero such as mean error, maximum error.

Can you explain for me?

I attach image to show VI, which I use.

Thank in advance.

Based off of the Perspective Calibration.vi example, it seems that you're using the IMAQ Get Calibration Info VI in the wrong place. I believe you should wire the VI after the Set Calibration Axis Info VI inside the While Loop. After I did this, I still saw all 0s for each Error Statistic. But, this makes sense because the calibration image is identical to the images looped through during pattern matching process. This also probably explains the strange behavior you were seeing in your own calibration setup.
