摘　　要：为了重建复杂形状的三维物体 ,在此提出了一种便捷的基于衍射光学元件 (DOE)色散成像特性的三维建模算法 ,该算法在一种新型的三维建模系统中实现 ,它充分利用了DOE在红外波段的模式投影和探测 给出了重建复杂形状的三维物体的仿真试验结果 。For the absolute and shape-free reconstruction of 3-D objects, a convenient 3-dimensional modeling algorithm is proposed and implemented in a novel modeling system, which takes full advantage of the chromatic dispersion characteristic of Diffractive Optical Element (DOE) for infrared wave band pattern projection and detection. Experimental simulation results demonstrate that the complex free-form shape 3-D objects can be reconstructed, and prove this algorithm and reconstruction system are effective and realizable.
