Preliminary study of multiview imaging for accurate 3D reconstruction using structured light scanner

Abstract

This paper presents a multi-view structured-light approach for surface scanning to reconstruct three-dimensional (3D) object using a turntable. It is a modification from DAVID 3D Scanner SLS-1 (Structured-Light Scanner) as a starting point of study on improving and builds a complete system of 3D structured-light based scanner. This type of scanner uses a video projector to project various patterns onto an object which is going to be digitized or reconstruct to a 3D model. At the same time, a camera will record and capture the scene at least one image of each pattern from a certain point of view for example from right, left, above or below of the video projector. Then, 3D meshes of surface of the object will be computed based on the deformations of the projected patterns. The preliminary results show that object which are model of prostheses are successfully reconstructed.
