Can I Acquire From Multiple Cameras in Vision Builder for Automated Inspection (VBAI)?



Primary Software:
Primary Software Version: 2.6.1
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem:
I would like to acquire from multiple cameras in my Vision Builder for Automated Inspection (VBAI) inspection. Is this possible?

Solution:
In VBAI, you can acquire multiple images by calling the Acquire Images step multiple times. This will work for multiple cameras and camera types (CameraLink, IEEE 1394, GigE, USB, and analog). Please note that the first time you call Acquire Images, you may need to select Multiple Channel Acquisition which can be found in the Main tab of the Acquire Images step. Once the images are acquired, you can call the Select Image step to switch between images and decide which image you would like to process.

It is important to note that VBAI limits each step to passing one image in and out. If you wish to perform an operation that uses two images (ex. subtract), you must use a custom LabVIEW step or you can also use a Vision Assistant step.
