3D-mode: a 3D modeling and measurement system using a few photos

Abstract

We demonstrate "3D-Mode," a software system that builds 3D models of objects and scenes by taking a few (minimally 2) photographs using a digital camera at possibly largely separated positions. It has recently been commercialized by 3D Media Co., Ltd. 3D-Mode has the following steps: (1) taking photos; (2) manually obtaining and matching a few feature points on the object; (3) automatically computing 3D structure and motion; (4) automatic Delaunay triangulation and manual modification; (5) automatic acquisition of texture for each triangular patch; (6) if necessary, assign a new coordinate system and scale of space. The system does not need input of camera parameters, but requires manual input of feature points in a special manner such that matching information is input simultaneously. Once epipolar lines are available, they are used to help locate corresponding points in other images.
