我们提出了一种新颖的绘画界面，使用户能够使用计算机控制的灯光阵列来设计真实房间的照明分布。用户通过在显示由安装在房间中的相机获得的图像的平板设备上绘制目标照明分布来指定房间的哪个区域将被良好照明以及哪个区域将被遮挡。绘制结果作为目标照明强度的轮廓线叠加在相机图像上。然后，系统运行优化以计算光参数以提供所请求的照明条件。实现了基于GPU的并行搜索，实现了实时处理。在我们的系统中，我们使用了可以改变照明方向的激励灯，以比静态灯更真实地生成所要求的照明条件。我们建立了一个微型实验环境，并进行了用户研究，将我们的方法与使用滑块的标准直接操作方法进行了比较。结果表明，对于非正式的灯光控制，用户更喜欢我们的方法。
We propose a novel painting interface that enables users to design an illumination distribution for a real room using an array of computer-controlled lights. Users specify which area of the room is to be well-lit and which is to be dark by painting a target illumination distribution on a tablet device displaying the image obtained by a camera mounted in the room. The painting result is overlaid on the camera image as contour lines of the target illumination intensity. The system then runs an optimization to calculate light parameters to deliver the requested illumination condition. We implemented a GPU-based parallel search to achieve real-time processing. In our system, we used actuated lights that can change the lighting direction to generate the requested illumination condition more faithfully than static lights. We built a miniature-scale experimental environment and ran a user study to compare our method with a standard direct manipulation method using sliders. The results showed that the users preferred our method for informal light control.
