Hi everyone,
Could somebody let me know how to find out the pixel size in Camera Calibration to accurate more?
The basic calculation what I know is below
"Square root of the area of the image pickup element divided by the number of pixels"
Then the parameter and the calculation will be...
---sample parameter---
Senser Size (mm) = 5.9 x 4.4 = 25.96 mm area
Resolusion size = 4608 x 3456 = 15925248 area
Formula
SQRT( 26 / 15925248 ) = approx "0.00127676"
----
However the parameter based on EXIF shows slightly different such as "0.00133853" as in attached photo.
So the questions are...
* Which EXIF parameter the Photoscan actually use for?
* Actual formula
---
I saw the thread below, and I would like to know more specific if i could.
