Augmented Reality and 3D modelling
Done by Stafford JoematSupervised 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.
