| 摘 要： | 本文提出了一种利用三维景物的二维视角投影图像合成计算全息图,并重构出彩色再现三维影像的方法.该方法基于利用视角投影图像获取景物的三维傅里叶频谱的理论,采用电荷耦合器件记录三维景物在白光照明条件下横、纵两正交方向的一系列视角投影图像,并利用这些视角投影图像合成计算全息图,从而重构出三维再现像,通过采用在频谱面上的容余采样...

| Abstract: | A novel method for the acquisition of full-color three dimensional(3-D) images of real objects was proposed based on multiple projections.In order to improve sampling efficiency,an orthogonal scanning mode was presented,instead of conventional 2-D scanning mode,to capture a series of projection images by a color charge coupled device in both vertically and horizontally direction with an incoherent light source.The 3-D Fourier spectra were extracted by using the projection images.The computer-generated holog... |
