Problems with match pattern

[erx]

What i need is:

1. Select Image01 and calibrate picture (select first and last point on the ruler and calculate how many pixels is in 1mm). DONE

2. Create template (from the hole) and save it into a file. DONE

3. Find similar pattern to created template (the second hole). NOT WORKING (Error -1074395989 occurred at IMAQ ReadImageAndVisionInfo

Unable to read data.)

4. Measure distance between the patterns( distance between two holes).

I uploaded pics and VI's to http://www.zone.ee/mahb02/ and also attached here.

The main VI is hole_distance.vi and the other two are sub VI's used inside main VI.

I would apprichiate, if someone could help me.

Thanks,

E.

Hi,

Seems like you save your template in a jpg file.

It should be a png because a lot more than juste the image needs to be saved in the template file.

Try the example you will find in

C:\Program Files\National Instruments\LabVIEW x.x\examples\Vision\2. Functions\Pattern Matching

Try using "IMAQ Write Image and Vision Info" instead of IMAQ writing a JPEG file. This includes all the pattern training information along with the image.
