In this paper, we propose a simple correction method of distorted elemental images for computational integral imaging reconstruction (CIIR) method by using surface markers on lenslet array. The position information of surface markers is extracted from distorted elemental images with geometric misalignments such as skew, rotation and so on. Then the elemental images can be corrected simply when applying linear transformation calculated from the extracted positions. Therefore, the proposed method can simply correct geometric misalignments such as skew and rotation. The corrected elemental images can provide the precise reconstruction of 3D plane images in CIIR. To show the usefulness of the proposed method, the preliminary experiments are carried out and the experimental results are presented. To the best of our knowledge, this is the first report to deal with compensating for the distorted elemental images recorded by using computational integral imaging.
在本文中，我们提出了一种简单的校正方法，用于通过使用微透镜阵列上的表面标记对计算积分成像重建（CIIR）方法中的失真元素图像进行校正。表面标记的位置信息是从存在诸如倾斜、旋转等几何错位的失真元素图像中提取的。然后，当应用根据提取的位置计算出的线性变换时，可以简单地校正元素图像。因此，所提出的方法可以简单地校正诸如倾斜和旋转等几何错位。校正后的元素图像能够在CIIR中实现3D平面图像的精确重建。为了证明所提出方法的有效性，进行了初步实验并展示了实验结果。据我们所知，这是第一篇处理使用计算积分成像记录的失真元素图像补偿问题的报告。
