我们提出了一种视网膜投影式超级多视图头戴式显示器（HMD）。超级多视图方法通过模糊视网膜图像来诱导人眼的调节，从而提供立体信息。该方法利用麦克斯韦视原理，通过在视网膜上叠加投影的视差图像来重建模糊图像。然而，仅仅考虑投影视差图像在视网膜上的重叠程度不足以重建真实的模糊。为了克服这一问题，我们提出了一种既考虑视差图像投影在视网膜上的重叠程度，又考虑视差图像的光强的最优方法来重建真实的模糊。通过评价实验，我们验证了与仅考虑视差图像投影在视网膜上的叠加程度的方法相比，提出的方法提高了模糊的再现性。此外，还证实了原型系统可以显示人眼可调节深度范围为200mm至2000mm的3D图像。基于该方法的超多视角HMD可以诱导人眼对高再现性模糊的调节，提供更自然的3D图像。
We have proposed the retinal projection type super multi-view head mounted display (HMD). The super multi-view method provides stereoscopic information by inducing the accommodation of the human eye by blurring the retinal image. This method uses the principle of Maxwellian view and reconstruct the blur image by overlapping projected each parallax image on the retina. However, considering only the degree of the overlap of the projected parallax images on the retina is not enough for reconstructing the real blur. In order to overcome this problem, we propose the optimal method considering not only the degree of the overlap of the parallax images projected on the retina but also the light intensity of each parallax image to reconstruct the real blur. From the evaluation experiment, we verified that the proposed method improves the reproducibility of blur compared to the method considering only the degree of superimposition of the parallax images projected on the retina. Furthermore, it was also confirmed that the prototype system can display 3D images in the depth range of human ocular accommodation from 200mm to 2000mm. The super multi-view HMD based on the proposed method can induce the accommodation of the human eye with the high reproducibility blur and provide more natural 3D images.
