This project, acquiring a photogrammetry-based 3D acquisition system (multi-camera computer vision 3D capture system) as a research instrument, aims to enable easy and repeatable collection of data across a wide range of research areas (Computer Science, Information Science, Geography, Environmental Science, Engineering, American Studies, Visual Arts, History, Library Science, etc.). The system consists of 96 synchronized cameras and associated flash and projection lights to capture a single object ranging from about 5 centimeters to several meters instantly. The flexibility of a photo-based system allows the same system to capture high resolution models over a wide range of scales, and to be equally useful for a single rigid object, an object in motion, or a person using a subject, object, or software, all with no object or subject preparation and minimal setup or reconfiguration.The scanning device is likely to have significant impacts: the projects on assistive technologies promise a lasting impact on disabled individuals; the brain imaging and genomics projects promise improvements on diagnostics health; the project will also have impact in the humanities, in understanding, and in documenting artifacts; and the digital library project will directly address how data generated by an instrument like this one can be preserved and referenced.Additionally, the project will have impacts on education and training of students. The center that will house the instrument has significant undergraduate staff who will be exposed to a state-of-the-art instrument and the research it enables. Undergraduate assistants, under the guidance of the center staff, will support the staffing for the instrument. Moreover, the instrument will impact several classes directly which will be able to use object and motion scanning equipment that is seldom available to undergraduates.

该项目将获得基于摄影测量的3D采集系统（多相机计算机视觉3D捕获系统）作为研究工具，旨在实现跨广泛研究领域（计算机科学，信息科学，地理学，环境科学，工程学，美国研究，视觉艺术，历史学，图书馆学等）的简单和可重复的数据收集。该系统由96个同步摄像机和相关的闪光灯和投影灯组成，可以立即捕捉从5厘米到几米的单个物体。基于照片的系统的灵活性允许同一系统在大范围内捕获高分辨率模型，并且对于单个刚性物体、运动物体或使用主体、物体或软件的人同样有用，所有这些都无需物体或主体准备以及最少的设置或重新配置。扫描设备可能会产生重大影响：关于辅助技术的项目有望对残疾人产生持久影响;脑成像和基因组学项目有望改善诊断健康;该项目还将在人文、理解和记录人工制品方面产生影响;数字图书馆项目将直接解决如何保存和引用这样的仪器产生的数据。此外，该项目将对学生的教育和培训产生影响。该中心将容纳仪器有显着的本科生工作人员谁将接触到一个国家的最先进的仪器和它使研究。本科生助理，在中心工作人员的指导下，将支持仪器的人员配置。此外，该仪器将直接影响几个班级，这些班级将能够使用本科生很少使用的物体和运动扫描设备。
