我们解决了一个严重影响深度融合三维(3-D)(DFD)显示器的问题，其中前、后平面之间的最大深度是有限的，因为不可能将前、后图像深度融合成一个3-D图像。我们还提出了一种用于这种深度DFD显示的感知模型。当平面之间的距离较大时，感知深度分为前平面附近、后平面附近和中点附近的位置。通过对前后图像进行空频调制，成功地扩大了最大深度范围。特别是，当前后图像的高频分量被空间频率调制切断时，即使在前后平面之间的大距离下，感知的深度也具有一个融合位置和线性相关性。
We solve a serious problem affecting depth-fused three-dimensional (3-D) (DFD) displays wherein the maximum depth between front and rear planes is limited, because depth fusing from front and rear images into one 3-D image becomes impossible. We also propose a perception model for this deep DFD display. When the distance between planes is large, the perceived depth separates into positions near the front plane, near the rear plane, and around the midpoint. The maximum depth range can be successfully enlarged by spatial-frequency modulation of the front and rear images. In particular, when the high-frequency component of the front and rear images are cut off by the spatial-frequency modulation, the perceived depth has one fused position and a linear dependence, even at large distances between the front and rear planes.
