If you’ve ever struggled with fSpy, had trouble getting a perfect match, and wondered why following tutorials doesn’t work for you - watch this.
You'll learn:
* what every single fSpy option means
* what are the common mistakes people make (both in fSpy and in Blender)
* how to deal with cropped images / shifted camera
* how to find the principal point (for 1-, 2- and 3- point perspective)
* how to determine the focal length if it's unknown
* why modeling from a 2-dimensional picture can lead to wrong object placement, and incorrect dimensions
* why setting the reference distance isn't enough
I believe this is the most complete fSpy tutorial at the moment and hope it will help you with your non-trivial images.
