Check Error on Camera View 1 in Multiview

    • New

    Hello & Happy New Year,

    i have a problem regarding my vision processes and checking the results.
    I have set up a multiview where i take 1 image at one position and the second image at another position.
    This is how i do it usually:

    Now this works perfectly fine but i have to go to another position even after camera view 1 failed to find a result in its edge locator.
    Is there a way how i can react after Camera View 1 has failed to get a valid result?
    I know there are instructions like GET_PASSFAIL but i dont get how exactly it works in a multiview since it will only take the whole multiview vision process as an argument?
    Unfortunately the roboter system with its camera is at the customer and i cant rly test out anything in advance... Only in my simulation with roboguide.

    Hopefully anybody has an example or solution to this?

    Thanks everybody and Best Regards
    Daniel

    Hello Daniel, Happy New Year!

    So, I already got some experience about vision processes, mostly in the software, and maybe I didn't understood what was your main question (English is not my main language), but if I got it right, when you do a multi view process, it considers the 2 cameras as being only 1, so if 1 fails it will consider was both failed,

    So I guess for the thing you want to do to, what I suggest is to do the 2 cameras separated, and then do a GET_OFFSET for which camera, that when a fail occurs in any camera, it will do a JMP LBL to somewhere

    I hope this is help you, even a bit, if not contact me back so I can see what is in my range:thumbs_up:

    Maybe not the cutest solution but you might be able to accomplish your task by doing something like this:

    1. Make a single view VP which looks for the same things as the first cam view in your multi-view VP (let's call this "VP_1")

    2. Go to Cam view 1 position and snap a picture and store it in image register 1

    3. Run VP_1 using the recently snapped picture that's now in image register 1

    4. Check PASS/FAIL on VP_1

    5. If FAIL, redo step 2 through 4

    6. If PASS, Run your multi-view VP with the picture in image register 1

    7. Move to Cam view 2 position and run find for that cam view

    8. Run Get_Offset on multi-view VP

    9. If it fails, then you know that it failed at Cam view 2.


    You need to use KAREL-programs for this, look in the iRVision Reference Manual (B-83914EN_09) for more info. The KAREL-programs are IRVSNAP and IRVFIND for executing the VPs and storing the pictures in img register as well as using a stored img to execute a VP.
