3-Dimensional Modelling and Visualization of Cultural Assets For E-Government

Abstract

A simple 3-dimensional (3-D) model construction technique using a line laser and a camera is presented in this work. By using the images captured under a controlled environment, showing the projection of the laser line onto the object surface, 3 dimensional graphical model and surface appearance are constructed for an object. A line laser, a digital camera and a turntable are used to constitute an image capture system. To construct more realistic models, a smaller turntable step size and a higher resolution camera should be used in the image capture system. In this work, the software required to construct the 3-D model from captured images of an object using an appropriate camera calibration technique has been implemented
