摘　　要：提出了一种基于正交柱透镜光栅的全视差立体成像方法。该方法采用3DMAX软件获取三维场景虚拟物体的多视角图像阵列。根据点阵合成法采用Matlab软件对视角图像的像素进行重组生成全视差像素，并对全视差像素进行拼接后获得全视差合成立体图。根据柱透镜光栅栅距的精确测量值对全视差像素的尺寸进行精确匹配，并用高分辨率激光打印机将全视差合成立体图记录在相片纸上，并将其与正交柱透镜光栅进行精确位置匹配。实验结果表明，从不同观察角度可观看到清晰、连续的具有全视差效果的三维再现像。A full-parallax three-dimensional （3D） imaging method based on orthogonal-stacked lenticular screens is proposed. Full-parallax images array of virtual object in 3D scene is obtained by 3DMAX software, and full-parallax pixels are generated by restructuring pixels of parallax images array using multi-dot synthetic method. Full-parallax pixels are synthesized together to generate full-parallax stereogram using Matlab software. The size of full-parallax pixel is adjusted to match the accurately measured value of grating pitch of the lenticular screens, and the full-parallax stereogram is printed onto the photo paper using high resolution laser printer. The position of the printed full-parallax stereogram accurately matches with that of orthogonal-stacked lenticular screens. The experimental result shows that reconstructed full-parallax 3D image can be viewed from different angles.
