This is an awfully vague question.  I'm not entirely sure what you are trying to do here.  If it is just image displays that you want, then I have attached a vi to display the images, you just need to specify the incoming image type.

Hi, tank you for your time to answer to my question. Actually i'm looking for a program to display two images took by two cameras at the same time on my vga screen. i'm using VBAI 2.6 and labview 7.6 . if you can help me.

tank you.

Tchaou.

Hello Tchaou,

Taking a look at the VI that you have attached, it appears that you are only working with one image.  Are you acquiring the images in VBAI and passing the files through to your LabVIEW code?  If you are acquiring from both cameras in LabVIEW, first you will need to create two separate buffers with unique names using the “IMAQ Create.vi”.  

If you are using analog cameras with our 1409/1410 frame grabber, I would take a look at the LL Scan Multiple Channels.vi in LabVIEW.  This can be found in the Example Finder using the task search under Hardware Input and Output >> IMAQ >> Low-Level folder. You should be able to modify this example to fit your application.  

If you are using firewire cameras you can use one of the basic Grab/Snap examples for the IEEE1394 or IMAQdx driver and duplicate the code for your second camera but remember to use a unique buffer name for this second buffer.  I hope this helps.  Please let us know if you would like further clarification or assistance.

Best Regards,

Vu D

Hi Vu D,

First thank you for your answer. you gave me informations that i ignored. i was wondering to display two images with this VI through VBAI wich is impossible because VBAI output one image once and not two. So tried to modifie just a litle bit this VI  because my main idea is to  split the monitor showing two images outputed by the VI that you saw. do you know any best way of doing that? if you want to see what modification i did with the VI you can see my question on the forum named: what's wrong with this VI.

Best regards.
