为了解决传统DFD显示在许多应用中存在的四个问题,我们提出并开发了一种“基于边缘的深度融合3d (DFD)显示”。1)通过调整形状相同的两幅重叠图像之间的亮度比例,以控制感知深度,可能会在重叠区域外出现模糊的双重成像和不适当的亮度分布。2)视角可能比较窄。3)最大感知深度可能受到限制。4)而且显示系统比较厚。“基于边缘”的DFD显示器,将所需的三维图像和相应的带间隙的边缘图像投影为二维图像,克服了问题(1),通过仅改变边缘图像的亮度来调整感知深度,从而使前后图像始终是清晰的二维图像。它还克服了问题(2)和(3),分别利用头部运动和/或通过模糊边缘图像。厚度问题(4)是通过融合一个DFD显示和一个弧三维显示来克服的。
We have proposed and developed an “edge-based depth-fused 3-D (DFD) display” in order to solve four problems in conventional DFD displays for many applications. 1) Obscure double imaging and an inappropriate luminance distribution may appear outside the overlap area due to adjusting the ratio of the luminances between the two overlapping images, which have the same shape, in order to control the perceived depth. 2) The viewing angle may be narrow. 3) The maximum perceived depth may be limited. 4) Moreover, the display system is rather thick. An “edge-based” DFD display, which projects a 2-D image of the desired 3-D image and a corresponding edge image with a gap, overcomes problem (1) by adjusting the perceived depth by changing the luminance of only the edge image so that the front or rear image is always a clear 2-D image. It also overcomes problems (2) and (3), respectively, by utilizing head movement and/or by blurring the edge image. The thickness problem (4) is overcome by fusing a DFD display and an arc 3-D display.
