Development of the three-dimensional scanning system based on monocular vision

The emerging three-dimensional (3D) scanning technology based on computer vision is attracting more and more attention in industrial applications such as the 3D modeling of motors and automobiles. This paper develops a 3D scanning system using monocular vision to rapidly and automatically obtain the 3D dimension of the scanned object. The principle of the 3D scanning system is firstly introduced. The structure is then presented. The system consists of a camera, a line laser generator, and a rotation platform with a direct-current motor. The software of the system is developed based on C # and EmguCV library functions to realize image processing. Additionally, experiments are carried out through a fabricated prototype. Experimental results demonstrate that the developed system achieves the rapid acquisition for the 3D dimension of the scanned object and features simple structure, low cost, easy to extend, and rapid 3D reconstruction.
