Augmented Reality and 3D modelling Done by Stafford Joemat Supervised by Mr James Connan and Mr Mehrdad Ghaziasgar

PROJECT OVERVIEW Marker-based Augmented Reality uses a camera and a visual marker, to determine the center of orientation and range of its coordinate system. The system is effectively a driver that allows users to superimpose a 3D object on a predefined marker, across multiple frames using fixed input video source.

Requirements Analysis Object Oriented Analysis Implementation Testing Issues User Manual ITRODUCTION

REQUIREMENTS ANALYSIS Equipment and Software needed High performance computer 2 mega pixel webcam AR marker with many good features Windows XP or better OpenCV library OpenGL Glut library

OBJECT ORIENTATED ANALYSIS

IMPLEMENTATION Extract frames Grayscale Feature detection Feature comparison Stabilized using a running average with selectivity.

IMPLEMENTATION Perspective comparison Draw 3D object and perform Perspective transformation Superimpose 3D object on extracted frames Display frames
