在各种应用领域中，高速摄像机被用来分析高速现象。已经提出了编码结构光投影方法来获取三维图像。它们大多数不适合测量高速现象，因为当被测物体由于多个图案的光投射而移动时会产生误差。在本文中，我们提出了一种新的编码结构光投影方法，该方法不仅可以自适应地选择时间编码，还可以自适应地选择空间编码，以高速帧速率获得三维图像。我们还开发了一个使用 DLP 投影仪和离线高速摄像机的评估系统，并通过显示获得的运动物体的三维形状来验证所提出方法的有效性。
In various application fields, high-speed cameras are used to analyze high-speed phenomena. Coded structured light projection methods have been proposed for acquiring three-dimensional images. Most of them are not suitable for measuring high-speed phenomena because the errors are caused when the measured objects move due to light projection of multiple patterns. In this paper, we propose a new coded structured light projection method that can select not only a temporal encoding but also a spatial encoding adaptively for obtaining three-dimensional images at a high-speed frame rate. We also develop an evaluation system that uses a DLP projector and an off-line high-speed video camera, and verify the effectiveness of the proposed method by showing the obtained three-dimensional shapes for moving objects.
