TLV3D

The idea - to map TLV in 3D using photogeometry.

We maintain the data on official TAMI superclusters and release it as emperors of the digital realm.

what already exists

metroscape has 3d models of a few tens of bldgs in tlv

googearth has also a few tens of tlv buildings

will goog come and nail it all down ? if we scoop them we get to ride in the google helicopter.

how to

The 3d scanners such as mantis and kinect are apparently not set up for long ranges like 10-50m which is what we're after to get buildings. Satellite photos probably are not of help here due to shallow angles and probable closed source-ness. A quadcopter may be of use but would take massive time and batteries. Rough order of magnitude of the problem:

one street every 50m

about 20km^2 of area in TLV

--> 800 km of street in TLV

--> a car / bike mounted 3d scanner is needed.

photogeometry

from several cameras with known relative angles and baseline, reconstruct 3d info using known algorithms

structured light

try to obtain 3d info from a large-ified kinect hack
