Typically those of us who travel a lot, whether it be for work or pleasure enjoy photography. How often have you looked over your photo’s from a trip and wished you could stitch them together digitally?
In an urban setting this could mean stitching together all the images of the Taj Mahal or of the Vatican, giving spatial clarity to urban area or gardens, laying out the 3-D space and size and enable one to zoom in on detail. Indoors this might this might enable one to visually walk around a space choosing to zoom in on detail or pull back to the broader perspective. A series of photographs taken over time could show different stages of development of an art project. Take the interior concept further and it could become a virtual guide to a museum, enabling a viewer to zoom in on the detail of artifacts as they choose.
If the concept is extended to landscapes, it wouldn’t take many photographs to complete a broad 3-D image and might enable the viewer to zoom in on photographs of activity, say canoers advancing down rapids, golfers moving over a course or climbers scaling a cliff. And the more photographs the greater the experience would be, photographs from different angles would all add to the 3D experience improving depth, scale, spatial dimensions and detail.
Thanks to Microsoft labs and Photsnyth this possibility is already a reality, though not commercially available. Scoble has posted a video of a demo by Gary Flake at the O’Reilly Web 2.0 Summit, or go direct to demo’s online. Photosynth software takes a large collection of photos of a place or an object, analyzes them for similarities, then displays the photos in a reconstructed three-dimensional space, showing you how each one relates to the next.
There are clearly many interesting practical applications one can imagine from monitoring environmental degradation, to observing flooding across an area relative to normal state or visually recreating the image of the Buddhas at Bamiyan after their destruction from multiple photographs, also see The Bamiyan Project to recreate them using computer graphics. Of course given a few professional tools the ability to use such imagery for measuring distances, or combine it with available remotely sensed data could potentially transform this into a powerful tool for post disaster assessment.
This is truly exciting, the next time you are part of a team that mobilises to assess a disaster, perhaps all those holiday snaps uploaded by tourists will provide detailed baseline data, improving effectiveness of response.
