Microsoft Photosynth is an software from Microsoft Live Labs and the University of Washington that analyses digital photographs to build a three-dimensional model of a photographed object. Pattern recognition components compare portions of images to create points, which are then compared to convert the image into a model. Microsoft states that the software will be web-based and rely on user-submitted digital photos.
As of November 9 2006 there is a free tech preview version available through Microsoft.
The program works by analysing multiple photographs taken of the same area. Each photograph is processed by noting specific features, like the corner of a window frame or a door handle. Photos that share features are then linked together in a web. When the same feature is found in multiple images, its 3D position can be calculated. Photosynth's 3D model is a cloud of points showing where these features are in space. This model enables the program to show a particular area from various angles, based on the different angles found in the photos. While the process works when only two photographs are used, it is better with more.
- Walk or fly through a scene to see photos from any angle.
- Zoom in or out of a photo.
- See where pictures were taken in relation to one another.
- Find similar photos to the one you're currently viewing.
- Send pictures.
