This Small Business Innovation Research Phase I project aims to develop the theoretical and practical bases for constructing a real-time, multiple camera, vision-based measurement system capable of providing accurate, three-dimensional measurements: (a) for verification of advanced modeling and simulation tools; and, (b) for remote, in-situ, non-destructive evaluation of both large and small structural components. The proposed research will focus on construction of a virtual test bed (VTB) for the vision-based measurement system. The VTB will include the processes of digital imaging, system calibration, image analysis for object measurement, and data synthesis for feature identification. We anticipate that results from the VTB development will identify promising concepts in each of these areas, which will be the focus of a Phase II program. Potential applications of the proposed measurement system technology include: (a) remote non-destructive evaluation (NDE) of civilian infrastructure; and, (b) validation of advanced computational models for a wide range of complex systems (i.e., full-scale bridge systems, tank cars, aerospace vehicles) under quasi-static and impact loading. In addition, the measurement technology is readily integrated with other measurement devices (i.e., temperature, pressure, ultrasound, acoustic) for development of a multi-level evaluation system.

该小型企业创新研究第一阶段项目旨在为构建能够提供精确三维测量的实时、多相机、基于视觉的测量系统开发理论和实践基础：（a）用于验证先进的建模和仿真工具;（B）用于大型和小型结构部件的远程、原位、非破坏性评估。本研究将针对视觉量测系统的虚拟测试平台建构进行研究。VTB将包括数字成像、系统校准、用于物体测量的图像分析和用于特征识别的数据合成等过程。我们预计，VTB开发的结果将确定这些领域中每一个有前途的概念，这将是第二阶段计划的重点。 所提出的测量系统技术的潜在应用包括：（a）民用基础设施的远程非破坏性评估（NDE）;以及（B）验证各种复杂系统的高级计算模型（即，全尺寸桥梁系统、坦克汽车、航空航天器）在准静态和冲击载荷下的性能。此外，测量技术易于与其他测量设备集成（即，温度、压力、超声、声学），用于开发多级评估系统。
