本文讨论了一种机器人视觉系统，它比大多数系统需要更少的计算能力。它利用在工作区域感兴趣的物体上印有染料的信托代码。染料在紫外线或红外线辐射下都会发光。印在这些物体上的发光信标代码是通过从一个发光的图像中减去一个没有发光的场景图像来识别的。工业应用包括实时识别、定位、组件定位和机器人定位，用于制造操作中机器人的视觉闭环控制。

A ROBOTIC VISION SYSTEM IS DISCUSSED WHICH REQUIRES MUCH LESS COMPUTATIONAL CAPACITY THAN MOST SYSTEMS. IT MAKES USE OF FIDUCIARY CODES STAMPED WITH DYES ON OBJECTS OF INTEREST IN THE WORK AREA. THE DYES WILL LUMINESCE UNDER EITHER ULTRAVIOLET OR INFRARED RADIATION. LUMINESCENT FIDUCIARY CODES IMPRESSED ON THESE OBJECTS ARE IDENTIFIED BY SUBTRACTING AN IMAGE OF THE SCENE WITHOUT THE CODES LUMINESCING FROM ONE WITH THEM LUMINESCING. INDUSTRIAL APPLICATIONS INCLUDE REAL TIME IDENTIFICATION, LOCATION OF, ORIENTATION OF COMPONENTS, AND LOCATION OF ROBOTS FOR VISUAL CLOSED LOOP CONTROL OF ROBOTS IN A MANUFACTURING OPERATION.
