Is there a tip sheet for using Zaraf?
We have created a movie to show the process steps of ZARAF using a scanned image from a 35mm format camera. In order to accurately measure scanned film negatives or scanned film prints in photogrammetry, the pixels must be square in format height and width. Zaraf is a software utility program that assures the pixels (rows and columns) are square. It is important to realize that “square pixels” are only part of the requirements for producing accurate photogrammetric XYZ coordinates. The focal length and lens distortion must also be solved; see iWitness’ “FOOM” process.
