Kite Aerial Photos

HQ FF2.0 kite and fuzzy tail with Pentax Optio W60 camera set to 'sports mode' and 10 second time interval.

Excavation of a Roman building.
Inverted kite aerial photo with the colour removed.

3D version (8.34MB pdf) Ctrl+left mouse button to move image, left mouse button to rotate, wheel to zoom.

Re-inverted still from the above 3D model.

Note that detail on the verticals is poor because the original photos were near vertical shots.

Still from a non-inverted 3D model looking in the opposite direction to the image above.

Still from a near infra-red 3D model (pdf 8.5MB).

As in the previous model, some verticals are 'smeared' because of the limited angles of coverage. This is because we used pre-existing images which were not intended for constructing models.

 

Crop Marks
