Pixel size
« on: April 29, 2023, 01:55:59 AM »
Hello,
I have some images that are downsampled from the native sensor resolution of 1920x1080 to 1280x720 to keep the FOV (Field of View).
The sensor pixel size is 1.4umx1.4um, what should I specify in the camera calibration dialog?

I was thinking:
1920x1080x1.4x1.4=4064256 (pixel area)
4064256/(1280*720)=4.41
sqrt(4.41)=2.1um=0.0021mm -> equivalent area?

What metadata are used to calculate the pixel size?
