Three Dimensional Measurements for Robot Vision (REU Supplement)

这项研究的目的是利用在以前的国家科学基金资助下获得的三维机器人视觉的发展。研究的一个领域涉及使用基于零件的CAD描述的形状投影模式技术检查加工零件。成形的图案以这样一种方式投射到制造的零件上，即使零件形状可能相当复杂，也会产生简单的图案，如线条或网格。简单的图案可以很容易地进行分析，以测试零件的形状质量与设计目标的比较。机器人控制的三维测量的其他方面也将被研究。这项工作为计算机辅助设计、制造和检验的整合迈出了重要的一步，并可能导致产品质量的提高和更大的经济竞争力。

The purpose of this research is to exploit developments for three-dimensional robot vision obtained under a previous NSF grant. One area of investigation involves the inspection of machined parts using the technique of a shaped projection pattern based on the CAD description of the part. A shaped pattern is projected on the manufactured part in such a manner that a simple pattern such as lines or a grid results even though the part shape might be quite complex. The simple pattern can be easily analyzed to test the quality of the shape of the part as compared to the design goals. Other facets of three-dimensional measurements for robot control will also be investigated. This work offers a major step toward the integration of computer-aided design, manufacturing, and inspection, and could lead to improved product quality and greater economic competitiveness.
