由于集成成像显示系统具有有限的景深，在微图像阵列获取与生成过程中，要考虑3D图像的重建深度，确保再现的3D图像在集成成像显示系统的景深范围内。当3D图像的重建深度与显示系统景深不适配时，需要重新调节拍摄参数以清晰地显示3D图像。为了避免对目标三维场景进行重新采集，提高微图像阵列生成效率，本文提出一种不同重建深度的微图像阵列生成方法。该方法通过调整图像元节距、调节相邻图像元间的视差值来改变光场的采样间隔，使微图像阵列可以适配不同景深的3D显示系统，提升集成成像微图像阵列的实用性。实验结果表明，该方法能实现不同深度的3D图像重建，验证了所提方法的正确性和可行性。

Since an integral imaging display system has limited depth of field, the reconstruction depth of 3D image should be considered in the acquisition and generation processes to make sure that the reconstructed 3D image is within the depth of field of the integral imaging display system. When the reconstruction depth of 3D image does not match the depth of field of the display system, the capture parameters need to be adjusted to display clear 3D images. In order to avoid re-acquisition of 3D scene and improve the utilization efficiency of elemental image array, this paper proposed a generation method of elemental image array for different reconstruction depths. This method can change the sampling interval of light field by adjusting the pitch of elemental image and the parallax value between adjacent elemental image, so that the elemental image array can be adapted to integral imaging display systems with different depth of field and improve the practicability of elemental image array. Experimental results show that the proposed method can achieve 3D image reconstruction with different reconstruction depths and verify the correctness and feasibility of the proposed method.
