Multiple Camera Acquisition in c/c++

[asmodi]

hello everybody,
while searching for solutions in this board i only could find hints for multiple camera
acquisition with labview. but i have to program in c/c++.
does anybody know where to find examples, tutorials or code snippets?

best regards,
malte

Malte,
attached you can find a CVI code for the 1408 and multiple channels (created with NI-Imaq 2.2). Maybe the source code helps you to create your own solution. 1409 is the follower of the 1408.

Note:
This sample demonstrates how to scan 1408 channels in multiple buffers using low level functions. The video sources need to use the same synchronization signals. The code scans from channel 0 on up until it reaches NUM_RING_BUFFERS.

The display is done using the function imgPlot, the canvas object is used to reserve some room on the panel. It is also possible to display the picture using a Canvas or a Graph. See the Display sub-directory.

Best regards,
Steffen

Hi,

I would like to run Multiple Camera Acquisition using NI-PCI 1410 and LabVIEW.

Is there anyone who could send me an example VI that opens  a camera session both on port 0 and port 1. I have tried img0::1 but did not find the port.

All channels are working fine in MAX.

Thanks,

Andras

Look for a separate channel input on the vi you use to configure the acquisition.  I don't think you need to create two sessions, since you can only do one independent acquisition at a time.

Thank you Bruce,

This is the solution! I have to use the channels.

It answeres my question posted on the thread below.

i need an example with two camson one IMAQ 1410

Thanks again,

Andras

You can't read two cameras at the same time with the 1410.

You can alternate between them if they are synchronized.  Synchronization makes both cameras start a new frame simultaneously and they use identical timing signals.  In this case, you can do a continuous buffered acquisition that alternates between the channels.
