I am struggling with calculating the size of objects in my P4P still photos.

Assuming a stock P4P camera, I should be able to determine a scale factor (inches/pixel) based solely on altitude.

Then, I just go into the image, count the number of pixels, and do the arithmetic.

Does this make sense? Does anyone know of a scaling factor table?
