增强现实 (AR) 的基本问题是如何自然地协调现实与用户所看到的虚拟内容。在采用光学透视头戴式显示器 (OST-HMD) 的 AR 应用中，这些问题通常会引发 OST-HMD 上的渲染颜色与输入颜色一致的问题。然而，由于各种显示限制和眼睛特性，在 OST-HMD 上难以区分地再现颜色仍然是一项具有挑战性的任务。解决此问题的一种方法是对输入颜色进行预处理，以便用户感知到显示器上的输出颜色与输入颜色相同。我们提出了一种 OST-HMD 的颜色校准方法。我们从对 HMD 和眼睛之间的渲染和感知过程中的物理光学进行建模开始。我们将颜色失真视为半参数模型，它将非线性颜色失真和线性颜色偏移分开。我们证明，校准后的图像在具有合成数据集和真实数据集的两个 OST-HMD 设置上恢复了原始外观。此外，我们分析了所提出方法的局限性以及 OST-HMD 中色彩再现的剩余问题。然后我们讨论如何为未来的 HMD-eye 系统实现更实用的色彩再现方法。
The fundamental issues in Augmented Reality (AR) are on how to naturally mediate the reality with virtual content as seen by users. In AR applications with Optical See-Through Head-Mounted Displays (OST-HMD), the issues often raise the problem of rendering color on the OST-HMD consistently to input colors. However, due to various display constraints and eye properties, it is still a challenging task to indistinguishably reproduce the colors on OST-HMDs. An approach to solve this problem is to pre-process the input color so that a user perceives the output color on the display to be the same as the input. We propose a color calibration method for OST-HMDs. We start from modeling the physical optics in the rendering and perception process between the HMD and the eye. We treat the color distortion as a semi-parametric model which separates the non-linear color distortion and the linear color shift. We demonstrate that calibrated images regain their original appearance on two OST-HMD setups with both synthetic and real datasets. Furthermore, we analyze the limitations of the proposed method and remaining problems of the color reproduction in OST-HMDs. We then discuss how to realize more practical color reproduction methods for future HMD-eye system.
