A range sensing technique is demonstrated that finds the 3-D shape of diffusely reflecting objects. The technique works sequentially in depth direction and is based on structured illumination and focus sensing. A TV camera and analog electronics are used to find the locations in focus of each step of a focus series in TV real time. The depth resolution is not very high, however, the technique is simple, rapid, and well suited to get an overview of a scene in robot vision.
一种距离传感技术被展示出来，它能找到漫反射物体的三维形状。该技术在深度方向上按顺序工作，基于结构化照明和焦点传感。使用一台电视摄像机和模拟电子设备实时在电视中找到焦点系列每一步的焦点位置。深度分辨率不是很高，然而，该技术简单、快速，非常适合在机器人视觉中获取场景的概览。
