Scanning-based 3D reconstruction of large-scale objects

Abstract

This paper designs a novel and practical 3D reconstruction system for large scale objects, where we make use of one 3D scanner, two guide rails, and one high precise motion control system based on PLC (Programmable Logic Controller) module. Two guide rails are parallel. The 3D scanner, used to reconstruct partial sections, is installed on the guide rails and uniformly moved by motion control system. The partial reconstructions are aligned according to uniform motion. The performance and effectiveness are evaluated by experiments. Compared with similar methods, our method has its advantages.
