I want to make a model building from a photo. I use fSpy for this.
But I can’t do it right. I tried different settings.
Photo of the building:
I set the X and Y axis. Principal point: Image midpoint
The Z axis is does not correspond to the corner of the building.
Mesh in Blender:
Principal point: From 3rd vanishing point. Set all 3 axes.
In Fspy, everything looks right:
In the blender, the photo is shifted to the side and the mesh looks bad:
Set the X and Y axis. Principal point: manual.
I moved the Principal point so that the z axis is at the corner of the building:
In the blender, the photo is again shifted and the mesh looks bad.
I ask for your help.
