Mathematical Sciences: 3D Scanning: From Physical Objects to Electronic Models

Stuetzle 9402734该项目的目标是开发能够实现快速、自动和廉价的“3D扫描”的方法；即，使用光学扫描技术从实物创建电子模型，例如汽车的粘土模型或涡轮叶片。3D扫描目前是一项重要的技术，用于美国的一些关键行业，如汽车和航空航天生产。然而，目前扫描仪硬件的成本和对广泛人工干预的需要阻碍了3D扫描发挥其全部潜力。我们的跨学科研究团队开发的方法将使3D扫描成本更低、速度更快、自动化程度更高。3D扫描的目标与计算机辅助制造相反：给定一个物理对象，如汽车、涡轮叶片、椅子或房屋的粘土模型，创建一个能捕捉其形状和颜色的电子模型。3D扫描目前是美国一些关键行业的重要技术，如航空航天和汽车生产。然而，目前扫描仪硬件的费用以及在数据收集和建模方面需要广泛的人工干预，阻碍了3D扫描发挥其全部潜力。这笔赠款将产生新的算法和软件，使新的扫描仪系统变得更快、更自动化、更小、更便宜，除了形状之外还能模拟其他视觉特性，并产生更高质量和更可用的输出。

Stuetzle 9402734 The goal of this project is to develop methods that will enable rapid, automatic, and inexpensive "3D scanning"; that is, the use of optical scanning technology to create electronic models from physical objects such as a clay model of a car, or a turbine blade. 3D scanning is at present an important technology, used in a number of critical US industries, such as automobile and aerospace production. However, the expense of current scanner hardware and the need for extensive human intervention has prevented 3D scanning from achieving its full potential. The methods developed by our interdisciplinary research team will make 3D scanning far less expensive, faster, and more automatic. The goal of 3D scanning is the inverse of computer aided manufacturing: given a physical object, such as a clay model of a car, a turbine blade, a chair, or a house, create an electronic model that captures its shape and color. 3D scanning is at present an important technology in a number of critical US industries, such as aerospace and automotive production. However, the expense of current scanner hardware and the need for extensive human intervention in both data collection and modeling has prevented 3D scanning from achieving its full potential. This grant will result in new algorithms and software that will enable new scanner systems that are faster, more automatic, smaller, less expensive, model other visual properties in addition to shape, and produce higher quality and more usable output.
