ReadBarcode (Invalid image type) Capture images with a prosilica camra

[Mike_Delau]

Hello everyone,

I'm a new user of Labview and making an application that reads barcodes via Prosilica camera, I made a VI, but it gives me the same error again and again.

I searched the site and found something about ROIToMask, but couldn't use it.

Can you please give me tips on how to do it.

I'm uploading the VI file.

I know that this might be an easy question, but I spend alot of time and at last I deceided to ask you guys.

Thank you

Hello Mike_Delau:

I checked your VI but unfortunately, I see no problem with the block diagram.
I would like to ask you a question though.
What error do you see?  Could you please provide the error code and description shown on the dialog box.

Thanks for your reply, I think that you are right, what I did was I changed the camera settings, so now it reads not as 16 bit, but as 8 bit.

But now I'm facing another problem with it, when the camera records it gives a message that says :

Not a linear barcode

unfortunately I'm not at the lab at this moment so I can't give you the number of the message, but it says as I mentioned. If I use the barcode example of the LabView it works ofcourse, but I justed changed the barcode example of Labview so that it shouldn't read from a file, but it should read via camera, but the Not a linear barcode comes!!!!!!

The VI file that I uploaded doesn't have any problems you are right but could you please give me some advice on how should I make this VI.

Thanks again

Mike

Hello Mike:

I think there's something wrong with your ROI.  LabVIEW might not able to acquire the correct barcode image.
Could you please send me an image that you acquire through your camera?

Hi Dehonair,

  Thanks for reply, I'm not at the lab right now that is why I can't send you the images, but I know where they are in Labview directory.

I used those images form C:\Programme\National Instruments\Labview7.1\examples\images\ I hope that I give you the right path, but if not it is just some where in examples of Labview.

I printed the images and then tried to read them via my camera.

Thanks again,

Mike
