Abstract :
This paper describes a computer vision method for reconstruction of three-dimensional object, this method can reconstruct the object real time and has high precision. In this approach the structured light is used and the light beam is projected to the surface of object. This work is composed of three parts: the first is the introduction of the light-section method and the experimental platform based on it. The information of the three-dimensional object surface can be acquired by the platform. In the second part a coordinate transformation algorithm is introduced, including camera calibration and calibration of the central axis of a turntable. And then the space information about object surface can be restored from the two-dimensional plane coordinate of the surface. Finally, a method for plotting the contour of the three-dimensional object surface using OpenGL is described in detail. In this paper, an experiment on a small flowerpot has been carried out and the three-dimensional contour of the flowerpot has been obtained. The result shows a high precision of the three-dimensional reconstruction.
