calibrate and display in real world units

[cees1910]

Hi ,

I Have a question about calibration and display the calibation in real world units

I calibrate a distance lt say for sake of the argument 157   pixels   that repressent  real world unit 0,76  meters.

How can i display that 0.76 meter (  its a diameter) as meters?.

all this with out doing the calc my selve  , this because i need to recalibrate often.

and it make's no sense in doing the calc my selve evrytime since the computer knows that 157 pixels represent 0.76 meters

Where can i pop up or select  to  display 0.76   ,   with out doing the calc my selve ?

Cees,

the vision development module has the IMAQ Convert Pixel to Real World VI function.

Hi,

In Vision Builder for Automated Inspection (VBAI) you can create a calibrated image which you then reference within all subsequent inspections. Using this technique you only need to create a new calibrated image (recalibrate) whenever there is a physical change to the inspection environment.

Any variables or calculation outputs can displayed using image overlay.

You haven't mentioned what software you're using.

Hope this is of some use.
