摘要：3D modeling of industrial parts is the key foundation and preceding step of 3D inspection and measurement of industrial parts. The common characteristic of industrial parts is that its surface is sleeky, homogeneous and lack of the texture. So the key difficulties in 3D modeling of industrial parts are the matching and the extraction of the suitable texture and the makeup of the 3D model. The paper proposes a flexible and practical method to three-dimensional model the small industrial parts based on the projector-camera system. The projector-camera system is composed of a slide projector, a digital camera, a control ground and a computer. After both calibrated respectively first, the projector-camera system is similar with the binocular vision system in the principle of 3D modeling. The 3D model of the target small industrial parts is acquired by connecting all neighbor space feature points and the real texture is rendered from relative images without the projected texture characteristic. The 3D modeling of small industrial parts is achieved finally. The method of 3D modeling is active and effective because the projected texture characteristic can be designed first on motivation. The 3D modeling method is non-touched so that it is remote and nondestructive. Because of little effect by the space factor or the time factor, the method of the small industrial parts 3D modeling is flexible and practical. The 3D modeling of small industrial parts proposed in the paper is confirmed to be correct and effective entirely by the results of the modeling experiments
