The easiest tool for simplest photogrammetric survey
Import the image in Rhad
(window-rose of the façade of Cathedral in Orvieto)
Take four points in clockwise order at the corner of a rectangle and run the rectification. The final image is rectangular with two unknown scale factors in the two main directions.
Then with the help of some geometrical constraints (a circle, a square, etc) correctly dimension the image
To get a stereo-partner, repeat steps 1, 2, 3, for the left image
