Augmented Reality and 3D modelling Done by Stafford Joemat Supervised by Mr James Connanand Mr MehrdadGhaziasgar
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.
ITRODUCTION • Requirements Analysis • Object Oriented Analysis • Implementation • Testing Issues • User Manual
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
TESTING THE SYSTEM • Test different depth • Test system with different markers • Test system with different objects
TESTING THE SYSTEM • Different depth test using Open GL 3D object used Background image Virtual Camera
TESTING THE SYSTEM • Test system with different markers Left Marker Right Marker
TESTING THE SYSTEM • Test system with different objects
USER MANUAL • Connect webcam • Get printed marker ready • Run executable • Put marker in front of webcam
