Camera Vision Loop Snap will be 1% right and left inverse in Vision2013 and Labview 2013.

[Peter123Chang]

Hello,

I use a Camera to Loop Capture Vision Snap in Vision2013 and Labview 2013.

(see the right-up picture that is the needle in the right side, but the right-down picture it is in the left side.)

The right-up picture that is the current snap image shows normally.

The right-down picture is after en-queued and de-queued image.

But the image will be 1 % Randenly Chance to show right and left inverse.

Could someone tell me how to solve the problem?

Thanks.

Hi Peter123Chang,

-Which camera model you are using? I have seen similar problem in one of the camera when trying to capture in labview it was inverted but when captured using their own software image was proper.
-Did you try with any other camera and it's the same or it's coming properly there.
-Post the VI in LV12 if possible so that i can help u better.

Good-day.

2 Cameras are both the same "AVT GUPPY F033B"  , Connected to the IEEE1394 interface PCI Card (2 ports, Controller Chip is Texas Instruments).(See" cam_driver.JPG")

Both Cameras are 1 % Randenly right and left inverse.(See" IMAG_Mirro_)_(2.JPG")

The Labview 2012 program is the attached file called "IMAGE_LOOP_SNAP_Queue As a Multiplexer_LV2012.vi.zip"

Thanks.

I didn't even run your code but the images looks ok.They are in normal, Please see the screenshot.

As far as code, it looks fine.

-The other possibbility might be, In MAX check Particular camera>>Camera Attributes>> Vertical Mirror option is unchecked.
