Re : Area Image Magic Wand Example

[eliel]

 I would like to use the example of labview "Magic Wand Example" to calculate the area that was selected.

How could I do that.

Thank you.

Hello,

You just have to pass the binary image created by the magic wand function to the IMAQ particle Analysis Report. You will have your area in pixels in the first element of the array.

I was able to measure the area in pixels but how can i do measure in cm ²?

What should I do to turn PIXEL in  AREA (cm ²)

Thank you

Hello

You have to calibrate your image in order to have a conversion from pixel to real world unit or vice versa.

Check the examples for that.

Once your image is calibrated, every function that output measurement of any kind will do it in real world unit.
