【SIGGRAPH Asia 2012专题】新兴技术之七：根据眼收敛的动态立体，多层次的图像显示







多层图形



本研究提出了一种简单的方法，如MRI影像显示体积数据。目前，3D表示双目视觉是很受欢迎的，但是，这种方法虽然可以显示三维表面模型，它是相当困难的，以掌握内部从一个三维结构的模型表示。此外，分辨率是不足够的许多实际应用中，如诊断。



另一种目前使用的方法是多层的图形，呈现的横截面的立体3D数据。一些体积的3D显示器能够显示这样的图形[1] [2]。传统上，许多类型的纺丝[3] [4] [5]或层叠[6]屏幕（s）已经被发明。然而，在实际使用中，它们太大。虽然使用的是商业的二维平面的方法是切实可行的，它要求的深度或索引的图像被显式地选择由用户[7]。因此，一个直观且简单的方法来选择的横截面图像是必需的。



为此，我们的想法是使用用户的eyes.As收敛的收敛是半自动根据图像的距离调制，它可以用来作为一个索引的图像的选择。



Multilayered graphics



This study proposes a simple method to display volumetric data such as MRI images. Currently, 3D representation using binocular vision is quite popular; however, although this method can display a 3D surface model, it is quite difficult to grasp the internal

s***cture of the model from a 3D representation. Furthermore, the resolution is not sufficient for many practical applications, such as diagnosis.

Another currently used method is multilayered graphics, which presents cross sections of volumetric 3D data. Some volumetric 3D displays are capable of showing such graphics [1][2]. Traditionally, many types of spinning [3][4][5] or stacked [6] screen(s) have been invented. However, they are too large in practical use. Although a method using a commercial 2D flat screen is practicable, it requires that the depth or index of the images be explicitly selected by the user [7]. Therefore, an intuitive and simple method to select cross-sectional images is required.

To this end, our idea is to use the convergence of the user’s eyes.As the convergence is semi-automatically modulated according to the distance of the image, it can be used as an index for image selection.
