在驾驶车辆时，如果驾驶所需的信息可以像增强现实（AR）一样显示，则驾驶员可以有效地操作车辆。例如，显示指示车辆接下来应该转向的交叉路口的图像是有效的。与传统的增强现实系统（如使用透视头戴式显示器）不同，目前用于车辆上显示速度表、转速表等的平视显示器（HUD）可以显示远距离视图的光学虚拟图像，并且覆盖大视场。但由于平视显示器的视场较窄，使其很难应用于增强现实。为了优化这一点，我们提出了一个系统，其中HUD被分成许多小的光学系统。应用与积分摄影（IP）类似的凸透镜阵列和元素图像。在产生虚像的每个透镜的前面对应一个元素图像。本文通过求解元素图像间位置关系的理论公式，生成连续的虚拟图像。此外，我们还用光线追迹法对系统进行了模拟。
In driving a vehicle, if the information which is needed to drive can be displayed like Augmented Reality (AR), driver operates the vehicle effectively. For example, it is efficient to display the images indicating an intersection where the vehicle should turn next. Unlike conventional AR system such as using See Through Head Mounted Display, Head Up Display (HUD) which is currently used on vehicle for displaying speed meter, tachometer and so on, can display the optical virtual images for long distance view and covers large viewing field. But it is difficult to apply HUD into AR because of narrow viewing field. To optimize this, we propose a system in which HUD is divided up many small optical systems. A convex lens array and elemental images which are similarly to Integral Photography (IP) were applied. One elemental image has been corresponding in front of each lens which generates the virtual image. In this paper, a theoretical formula of the position relation among the elemental images was solved to create the continuous virtual images. Moreover, we simulated the system with ray tracing method.
