Real-time 3D modelling
A group of researchers at the Department of Engineering at Cambridge University have created a program that is able to build 3D models of textured objects in real time
A group of researchers at the Department of Engineering at Cambridge University have created a program that is able to build 3D models of textured objects in real time, using only a standard computer and webcam.
The development is expected to aid in the creation of virtual 3D models, a process that often requires heavy and expensive equipment, or is time consuming.
Qi Pan, Dr Gerhard Reitmayr and Dr Tom Drummond presented the system at the 20th British Machine Vision Conference in London.
During the last few years, many methods have been developed to build a realistic 3D model of a real object, using equipment including 2D/3D lasers, scanners, projectors and cameras.
These pieces of equipment are usually expensive, complicated to use or inconvenient and the model is not built in real time. The data (for example, laser information or photos) must first be acquired, before going through a lengthy reconstruction process to form the model. If the 3D reconstruction is unsatisfactory, then the data must be acquired again.
