In particle analysis, you can get the bounding box left,right,top and bottom of particles which might be the answer u r looking for.

 

If not,Can you please post the vi also if possible??

Thanks

Hello,

 

why do you need the "internal" box? This would be in my opinion difficult to implement as a general solution. What if there is a larger degree of "rotation"?


If you want to process the thresholded area further, you should use a masked image (you can convert the mask to ROI). This enables you to define the rotated regions also.

Hello, 

 

I have to accept nut having diameter 1cm and reject other nuts , if I place them in front of my camera  using particle analysis.

I have Labview 2012 version and Camera used is Basler aca 2000-50gc .I tried to make a VI by using concepts of " Particle analysis .vi " example, but it is not showing proper results. 

 I am attaching my VI and  Image of nuts .

 Please suggest me modifications as soon as possible.

 

Thanks.

I'd recommend asking this on a new thread in the Machine Vision forums. This will bring it to more attention than tacked on to an old one. Also, please give more details in the new thread of what is not working in your inspection and prepare a version of code to read the image from file so that forum if you want users to run your VI.
