提出一种基于相位辅助系统的三维纹理重建方法,将采集到的纹理照片映射到几何模型表面,以实现对几何表面的纹理色彩的融合处理。建立了纹理映射优化函数,优化了目标物体和纹理照片的映射,并通过纹理融合处理,在最大程度上保证了目标物体纹理的逼真度,最终可得到逼真的三维物体纹理重建结果。还对局部缺失的目标模型或未采集到的局部纹理进行了修复,实现了三维纹理表面的自然过渡,从而保证目标模型纹理的完整性和一致性。不同类型实物的实验结果均证明该本文算法的可行性和有效性。

A computer generated holographic stereogram based on the wavefront recording plane (WRP) is presented. A WRP closed to the parallax image plane is introduced to record the complex amplitude in a small region for each point in the parallax image. By using three times of fast Fourier transform (FFT) to execute the Fresnel diffraction calculation between the WRP and the holographic stereogram plane, the object wave contributing to the hologram pattern can be achieved. The computation complexity of the proposed approach is dramatically reduced. The results show that the calculation time can be decreased by more than one order of magnitude.
