Image Processing (Corner Detection)_NI Vision Assistant

Dear Friends,

 

Please have a look of my attached Image.

  1. I would like to detect points
    1. Upper points 1,2,3,4,5
    2. Lower Points 1,2,3,4,5
    3. Middle point 11
  2. Then I would like to connect
    1. Upper point 1-->Lower Point 1
    2. Upper point 2-->Lower Point 2
    3. Upper point 3-->Lower Point 3
    4. Upper point 4-->Lower Point 4
    5. Upper point 5-->Lower Point 5
  3. After connecting I would like to measure the horizontal distance from point 11 to the connected lines (Either (+) or (-))

I would like to know, whether it is possible in Ni Vission Assistant or NI Vision Builder and (The scale of the lines and the angle of the lines might vary, but anyhow there will be 10 connected points (Upper 5, Lower 5).

 

It would be great, If you listdown the steps to do it or a sample demo.

 

 

Thank you,

 

 

 

Best Regards,

Rathan

Interesting question. First vision assistant is only playing around with image processing functions and generate a vi if needed. For building a solution you will require labVIEW anyway.

 

One thing you can try is clamp the image and you will find the height. With this you find the centre point. With a reference you can find try finding the straight edges. Can you post the original image so that i can try working on that?
