I shot a series of photos around the Etoile at the center of which stands this grand monument. It is incredible how busy the traffic is here at all hours, both vehicular and pedestrian! Anyway, from this series I was able to generate a point cloud to describe this massive arch at the head of the Champs Elysee. I then scaled the entire affair based on measurements taken from Google Earth.
I also shot the ‘undercarriage’ of the monument to create a point cloud describing the vaulted surfaces there using photogrammetry. The point cloud itself is dense enough to create a sort of drawing. The location of any additional points – or edges etc. – can then be easily (an accurately) queried directly from the photographs.
