Machine Vision Assistant - 1 pixel = ? mm

[Maybach]

I am using a monitor of resolution 1920 x 1080 with length of the monitor is 47,6 cm

then.

When I am starting the vision assistant to measure of certain length. It has only pixels unit.

and the resolution of the image in vision assistant is 1384 x 1033

So I am willingly to know conversion between 1 pixel = ? mm

I made a search, and it told me to do a calculation of 

47,6 : 1384 = 0.0343930......cm

is this correct?

Thank you.

Hi,

If you want to be able to measure your distances in world units, you will have to calibrate your image first.

See here [link removed; article no longer available] for more details.

Once done, the calibration will be detected by other IMAQ functions, and the results will be available in both pixel and world units.

...in the forum that this problem is resolved, I've also been working for some time with high resolution Acama, with adequate lighting and digital zoom I can get 1mm menorahs measures nevertheless a margin of error brings , one might solve this?
