Augmented reality-landmark estimation

Augmented Reality means interacting with the real world circumstances and virtual objects at the same time which is augmented by system generating inputs. That is, it allows the system generated content to be superimposed over a live camera of the real world. It is an absolutely graphical experience that is combined with real world circumstances. Here, the landmark will be acquired as an input of the image by sight-based camera parameter estimation methods by using SFM (STRUCTURE FROM MOTION) technique. In this paper, we are going to overlay real still images of landmark with virtual computer graphical images. These SFM techniques which have been discussed earlier in some of the previous papers will not work in real time applications because of its high cost. But here, this method will achieve fast and accurate landmark estimation based on SFM and we obtain the 3-D structure of a landmark by using this technique which has no need of information about the scene.
