new to NI vision builder: Calculating the area of a component

[stealthengineer]

Hi all,

I am new to this whole NI vision builder. I would like to  know what are the steps that need to be taken to calculate an area of a component.

Thank you

first you have to calibrate your image and after that if you want to do your calculation automatically should use some binary action and some particle detection algorithm exist in morphology

The Detect Objects step located in the Locate Features tab returns the area of objects. As Hatef mentioned, you must calibrate the image first if you want to get results in real-world values.

Check out the following examples:

Hope this helps.
