利用相机阵列获取三维信息实现三维集成成像与显示时，为消除相机阵列空间位置偏差对元素图像阵列的影响，提高再现三维图像的质量，以相机阵列记录系统为基础提出了一种元素图像阵列校正方法。通过特征点位置坐标以及相机位置平移误差和旋转误差的计算，分析了相机阵列位置平移误差和旋转误差与元素图像间的关系，以及校正算法的精度。利用光学实验对该算法进行了验证，结果表明，此方法可有效消除相机阵列位置偏差对元素图像阵列的影响，并且校正后再现三维图像质量明显优于误差图像，峰值信噪比提高了33.6%，实现了基于三维集成成像相机阵列获取的元素图像校正，满足了集成成像的显示要求。

A method is presented to correct the errors of elemental images due to position deviation of cameras in the process of camera array pick-up of three-dimensional (3D) integral imaging. By calculating position coordinates of reference points and position errors of camera array, the accuracy of correction algorithm and the relationship between position errors of camera array and elemental images are analyzed. Optical experimental results verify the feasibility of the proposed method. The results show that, the proposed method can effectively eliminate the effect of position deviation of camera array on the elemental images array and the reconstruction 3D images with better quality can be achieved after correction. The comparison of reconstruction 3D images before and after correction indicates that the errors of elemental images captured by camera array are corrected successfully with value of peak signal to noise ratio 33.6 percent improved, which can satisfy the display requirement of integral imaging.
