PhotoBuilder

This concept of using the mathematics of linear perspective to create three dimensional models from two dimensional scenes has been taken further to automatically build three dimensional models of architectural scenes from photographs. This can be accomplished using two or more arbitrary photographs of a building from an uncalibrated camera.

For instance, this three dimensional model of Jesus College chapel in Cambridge was built up from the two photographs shown. Free software, known as Photobuilder, is freely available for download. Try it out on your own home or favourite building.

It is hoped that this type of software will be of use to architects and estate agents as well as custodians of important buildings.
