In order to compensate the lens axial position error in macrolens array based integral imaging display system, a calibration method of the reconstruction degradation caused by the lens axial position error is proposed. The dispersive spot size of a reconstructed point is employed as a measurement metric to investigate the characteristic of the reconstruction degradation, and further calibration of the elemental image pixel remapping algorithm is proposed to compensate the lens axial position error, where the real working distance between the lens and liquid crystal display (LCD) is measured, and the elemental image pixels are rearranged accordingly. The experimental results show good agreement in the theoretical prediction of reconstruction degradation and indicate that the proposed calibration method can effectively reduce the influence of the lens axial position error and improve the reconstruction quality of the integral imaging display system.

为了补偿基于大透镜阵列的积分成像显示系统中的透镜轴向位置误差，提出了一种由透镜轴向位置误差引起的重建退化的校正方法。以重建点的色散点大小作为测量指标，以研究重建退化的特征，并提出了对基本图像像素重新映射算法的进一步校准，以补偿镜头轴向位置误差，其中镜头之间的实际工作距离为测量镜头和液晶显示器（LCD），并相应地重新排列基本图像像素。
