Is it possible and how can I infer a parameter like the distance or the illumination from the chart, by looking at the metadata of the picture ?
To give some context, I am working on a chart with smartphones, a chart mainly looking like the e-sfr ones. I have aruco markers all around which I know are exactly 1cm a side. I also have MTF plots for this chart.
Looking at EXIF data I have lots of information like F-stop, exposure time, ISO, focal length, ... Is it possible to compute external parameters from these ?
