Hi, To be honest I don't know how well calibration will work on those photos. The brick lines wont quite be straight but the distortion is on a much larger scale than the brick variation, so it might produce a good answer anyway. I can do the calibration for you, but I don't have a lot of time and it might be a week or more before I can do it. You mentioned glass walls in your mail and they tend to have much larger and more regular panels than brick, so if you do run the shots again, that might be better.
Have you had a look at https://wilson.bronger.org/calibration? That gives details of a place that you can upload images for calibration. That's really the right place to upload photos, but since I've lost my password for that image store at the moment I'll take these photos from here.
