为了使广义增强现实可行，增强元素必须在各种环境中以及在快速变化的高动态范围照明下可见，从明亮的阳光到深阴影。我们提出了一个高动态范围，光学透视，增强现实显示器，动态调整的亮度的虚拟图像，以匹配当前亮度的真实的场景。关键部件包括空间亮度传感器阵列和位置亮度图像强度匹配器。彩色、场景自适应HDR显示系统基于使用高速RGB LED照明器的高速率（15 kHz）DMD投影仪，对于每个二进制DMD帧，每个颜色具有独立的16位强度控制。强度匹配算法的关键输入是高灵敏度光传感器阵列的输出。本文讨论了该系统的实施和报告性能通过静态和视频演示在各种照明条件下。
For generalized augmented reality to be feasible, the augmenting elements must be visible in varied environments and under rapidly changing, high dynamic range lighting, from bright sunlight to deep shadows. We present a high dynamic range, optical see-through, augmented reality display that dynamically adjusts the brightness of the virtual imagery to match the current brightness of the real scene. Critical components include the spatial brightness sensor array and the positional brightness image intensity matcher. The color, scene-adaptive HDR display system is based on a high-rate (15 kHz) DMD projector using a high-speed RGB LED illuminator, each color with independent 16 bit intensity control for each binary DMD frame. The critical input to the intensity matching algorithm is the output of an array of high sensitivity light sensors. This paper discusses the implementation of the system and reports performance via still and video demonstrations under a variety of lighting conditions.
