Integral imaging three-dimensional (3D) display provides quasi-continuous viewpoints within a certain viewing angle. A single human eye can obtain several parallax images corresponding to the viewpoints. In this paper, we studied the effect of viewpoints received by a single human eye on the accommodation response when viewing the 3D image reconstructed by integral imaging 3D display. We analyzed the viewpoints distribution of an integral imaging 3D display and the correspondence relationship between the viewpoints and pixels information in elemental image array. In the experiment, the accommodation responses of human eyes when viewing the 3D image with different viewpoint quantities and dimensions are measured. The statistical results reveal that the more viewpoints received by a single human eye, the closer the accommodation response of the 3D image is to that of the real target. This tendency is obvious when the viewpoint quantity reduces from 10 × 10 to 6 × 6. For situations of 2 × 2 and 1 × 1 viewpoint, the accommodation response is unstable and different from the real target. When considering the viewpoint dimensions, two-dimensional viewpoints can provide a more natural accommodation response than one-dimensional viewpoints do. For the one-dimensional viewpoint situation, the horizontal arranged viewpoints and vertical arranged viewpoints have no statistical discrepancy.

积分成像3D显示中视点对调节响应的影响

整体成像三维 (3D) 显示在特定视角内提供准连续视点。单人眼可以得到多个视点对应的视差图像。在本文中，我们研究了在观看由积分成像 3D 显示器重建的 3D 图像时，单人眼接收到的视点对调节响应的影响。我们分析了整体成像3D显示器的视点分布以及元素图像阵列中视点与像素信息的对应关系。在实验中，测量了人眼在观看具有不同视点数量和维度的3D图像时的调节反应。统计结果表明，单眼接收到的视点越多，3D 图像的调节响应越接近真实目标的调节响应。当视点数量从 10×10 减少到 6×6 时，这种趋势很明显。对于 2×2 和 1×1 视点的情况，调节响应不稳定，与真实目标不同。在考虑视点维度时，二维视点可以提供比一维视点更自然的调节响应。对于一维视点情况，水平排列的视点和垂直排列的视点没有统计差异。在考虑视点维度时，二维视点可以提供比一维视点更自然的调节响应。对于一维视点情况，水平排列的视点和垂直排列的视点没有统计差异。在考虑视点维度时，二维视点可以提供比一维视点更自然的调节响应。对于一维视点情况，水平排列的视点和垂直排列的视点没有统计差异。
