These windows were extracted from a 360-camera suitable for google-streetview (e.g. a GoPro MAX360 or a LabPano Pilot camera ).
Building facades were extracted then automatically rectified using GIS building footprints from OpenStreetmap.
Finally, the facade rectification was refined based on on edges in the image.
Each window was manually outlined (however we found that window bounadries can be difficult to precisely define due to semantics).
Each window was also manually tagged based on its shape.
The data exists as a large zip file at psv-v1-windows.zip
