项目摘要

We studied a 3-D display that uses two stereoscopic displays at different depths aiming at the eye strain-free head mount display and found as follows. 1) Two same-shaped 3-D images displayed at different depths by the two stereoscopic displays were fused into one 3-D image when they were viewed as overlapping. 2) The perceived depth of the fused 3-D image depended on both the luminance ratio of the two 3-D images and their original perceived depths. These depth fusions were observed under conditions where the distance between the original perceived depths of the two 3-D images was short, i.e., under ten percent of the distance between the observer and 3-D display. 4) For a long distance between their original perceived depths, two 3-D images did not fuse into one image. However, they were closer to each other than their original positions.We applied a model in which the human visual system uses a low-pass filter to perceive the fused image, the same as that used for a conventional DFD display. The simulation results revealed that the perceived depth of the fused image changed depending on both the luminance ratio of the two 3-D images and their original perceived depth and the low-pass filter model accurately presented the perception of a 3-D image on our 3-D display. We also proposed a model for conditions where the two 3-D images do not fuse. When the human visual system undertakes binocular matching in this model, it selects the wrong pair of edges. That is, it sees the two edges of patterns displayed at different depths as the same edge, although they are the edges of different patterns. The simulation results revealed the proposed model accurately presented depth perception.

我们研究了针对眼睛无应变头戴式显示器在不同深度使用两个立体显示器的3-D显示器，并发现如下。1)当两个立体显示器在不同深度处显示的两个相同形状的3-D图像被视为重叠时，它们被融合成一个3-D图像。2)融合的3-D图像的感知深度取决于两个3-D图像的亮度比和它们的原始感知深度。这些深度融合是在两个3-D图像的原始感知深度之间的距离很短的条件下观察到的，即，低于观察者和3D显示器之间距离的10%。4)对于原始感知深度之间的长距离，两个3D图像不会融合成一个图像。然而，它们彼此之间比它们的原始位置更接近。我们应用了一种模型，在该模型中，人类视觉系统使用低通滤波器来感知融合图像，与传统的DFD显示器相同。仿真结果表明，融合图像的感知深度随两幅3-D图像的亮度比和原始感知深度的变化而变化，低通滤波器模型准确地反映了3-D图像在3-D显示器上的感知效果。我们还提出了一个模型的条件下，两个3-D图像不融合。当人类视觉系统在该模型中进行双目匹配时，它选择了错误的边缘对。也就是说，它将在不同深度显示的图案的两个边缘视为同一边缘，尽管它们是不同图案的边缘。仿真结果表明，该模型能够准确地呈现深度感知.
