Augmented Reality for 3D construction

Augmented Reality is an emerging field with a wide range of applications. It involves the process of merging virtual components with the real world objects so that the user is unable to distinguish the change in the real world. The virtual component augmented is usually interactive in nature. This gives the user a feeling that the object is present in the view even though it is physically absent. Here we have explained about performing augmentation of the virtual object on the live camera feed. The Structure from Motion (SFM) technique is used for the purpose of estimation of the parameters of the objects, which describe the position and orientation of the virtual component that is overlaid on the real environment. This technique uses specific symbols called as markers which help in the placement of virtual object in the real world. (C) 2012 Published by Elsevier Ltd.
