Select VBAI camera from LabVIEW

[tr_dane]

Hi Clemens,

I attach my .vi. VBAI will run for each side(camera position); TOP,LEFT,RIGHT once button is pressed. Is this method that you and the others recommend ?

Another solution is to have one inspection per camera

You just need to have multiple acquisition steps; one acquisition step for each camera.

Any advice would be greatly appreciated...

Thanks,

If you open a different session to each inspection, it will be much more efficient. I attached an example of this. This assumes that none of the inspections use shared resources that can't be accessed at the same time (i.e. they use different cameras), otherwise the first inspection opened will get exclusive access to the resource and the other inspections will fail to load.

If this is a problem, you can also have all three camera acquisitions/processing within a single inspection and use the Set Variable VI in LV to determine which transition to use. I attached a sample image of the state diagram to illustrate this approach.

Hope this helps,

Brad

Are the 3 inspection sequential? Your sentence seem to mean that you acquire from one camera, move, acquire from the second, move, then acquire from the 3 camera.

Is that the case? How does the motion come into play?

Also, do you plan on driving the motion from VBAI, or from LabVIEW?

These details might help us recommend the best design.

Thanks a lot Brad, I will look into your suggestions.

Exactly, Christophe!

I want to use Arduino+Ramps 1.4 (low-cost), since the microcontroller usually use as 3D printer motion controller.

So, I plan to load Coordinate/position from LabVIEW to the microcontroller to move the camera to specific point.

1. Once on first point, signal triggers LabVIEW to call VBAI to do acquisition on that point.

2. Next, move to the next point, and the next camera will do acquisition.

In the end, if all Three Camera Inspection PASS it means the product is pass the inspection.

If One/two camera Inspection FAIL means the product will need to rework.

Is this concept/idea can be done? or is it too ambitious? I learn to use LabVIEW mostly from this forum.

Thanks in advance!

Hi again,

I decided to try the second option you suggested.

But, im having a hard time to find this palette .

Also in VBAI, the first state check variable state, transition state check, can you provide an example for this. 

Thanks, again !

Here's a sample of how to use Set Variable from LV to change the inspection in VBAI.

Hope this helps,
