在大幅面集成成像显示系统中,宏透镜阵列位置误差会严重影响成像质量。宏透镜阵列位置误差可以分为轴向位置误差和横向位置误差,理想情况下汇聚于重构点的像素在位置误差作用下将不再汇聚,这些像素将在其他点处成像。本文利用重构点到这些点的距离的平均值和方差对位置误差的大小进行了度量,并讨论了宏透镜阵列轴向位置和横向位置的测量方法,给出了宏透镜阵列轴向位置误差和横向位置误差的校正方法,从而缓解了宏透镜阵列位置误差对成像质量的影响,提高了显示效果。
In the large-format integral imaging display system, the position error of the macro lens array will seriously affect the imaging quality. The position error of the macro lens array can be divided into axial position error and lateral position error. Pixels converging at the reconstructed point ideally will no longer converge with the position error, and will be imaged at other points. In this paper, the average and variance of the distances from the reconstructed point to these points are used to measure the size of the position error. In addition, this paper discusses the measurement methods of the axial and lateral positions of the macro lens array, and then gives the correction methods of the axial and lateral position errors of the macro lens array, thereby alleviating the influence of the macro lens array’s position error on the imaging quality and improving the display effect.
