Image resolution changed after image calibration

Go to solution

Hi all,

I set my webcam resolution to 1280x720 but after Image Calibration, the video changed to 1364x730.

Does this affect to the coordinate of pattern matching? It's very important in my application.

BTW, in Pattern Matching 4, there is an output of Matches (real-world), how to give it information to translate from pixel into mm? Currently I'm using pixel matching and use some calculations to translate the matching result into mm. And where is real-world coordinate origin? Is it also at the left top corner like pixel coordinate?

You can try using the "IMAQ Convert Pixel to Real World VI" to transform pixel coordinates to real world coordinates.


Best regards.
