Abstract

When a speaker stands in front of a projector screen for a presentation, the eyes will be hurt by the direct light from the digital projector. This paper proposes a design to reduce the strong light by projecting a black round mask on the speaker's head. The black round mask is superimposed to the slide frame by the software of this design and the mask traces the speaker's head. The depth camera captures the depth images from the speaker with the projector screen. The location of the speaker's head is determined by using the middleware components to process the depth images. This design efficiently continues to trace the head location. The computer uses this head location and superimposes a black round mask to reduce the uncomfortable feeling caused by the strong light of the projector.

使用深度图像处理和人体骨骼识别方法来减少来自数字投影仪的不舒服光线
当演讲者站在投影仪屏幕前进行演示时,眼睛会受到数字投影仪的直射光的伤害。本文提出了一种通过在说话人头上投射黑色圆罩来减少强光的设计。本设计的软件将黑色圆形掩模叠加到幻灯片框上,掩模沿着说话人的头部轨迹运动。深度摄像头通过投影仪屏幕捕捉扬声器的深度图像。通过使用中间件组件处理深度图像来确定扬声器头部的位置。这种设计有效地持续跟踪头部位置。电脑使用这个头部位置,并叠加一个黑色的圆形面具,以减少投影仪强光引起的不舒服的感觉。
