This Small Business Innovation Research Phase II project will develop an innovative Photogrammetry Data Acquisition and Processing System for special areas of highway design. To design and maintain transportation systems, three-dimensional data on specific areas are collected by means of aerial photography, manual surveys, and labor intensive data processing. The current aerial photography methods, however, are not capable of collecting data on areas that may not be seen readily from an aerial position, such as bridges and rock faces. The goal of the proposed project is to develop a portable, easy-to-use, digital camera-based system that used close-range photogrammetry techniques to accurately model these areas. The proposed data acquisition system consists of a high resolution digital camera, total station, and a photogrammetry calibration target, as tested during the Phase I program. The feasibility of such a system was also demonstrated by a highway experiment conducted while receiving assistance from the New York State Department of Transportation (NYSDOT). A novel feature of the proposed system is that it is tailored to the accuracy desired for different applications through the use of a mathematical model. The main research objectives focus on implementing, testing, and improving methods to obtain accurate camera position and orientation data, and developing an innovative method of automating 2D point correspondence in digital images. The new prototype system offers significant labor and time savings in gathering photogrammetry and ground survey data. Potential commercial applications of the research include assessing bridge condition, modeling rock faces, reproducing crime scenes and archeological objects.

这个小型企业创新研究第二阶段项目将为高速公路设计的特殊领域开发一个创新的摄影测量数据采集和处理系统。 为了设计和维护运输系统，通过航空摄影、人工调查和劳动密集型数据处理收集特定区域的三维数据。 然而，目前的航空摄影方法不能收集从空中位置可能不容易看到的区域的数据，例如桥梁和岩石表面。 拟议项目的目标是开发一个便携式，易于使用，数码相机为基础的系统，使用近景摄影测量技术，准确地模拟这些地区。 建议的数据采集系统包括一个高分辨率的数码相机，全站仪，和摄影测量校准目标，在第一阶段计划的测试。 在得到纽约州交通部（NYSDOT）援助的情况下进行的高速公路试验也证明了这种系统的可行性。 所提出的系统的一个新的特点是，它是专门为不同的应用所需的精度，通过使用的数学模型。 主要研究目标集中在实现，测试和改进方法，以获得准确的相机位置和方向数据，并开发一种自动化的数字图像中的二维点对应的创新方法。 新的原型系统在收集摄影测量和地面测量数据方面节省了大量的人力和时间。 该研究的潜在商业应用包括评估桥梁状况，建模岩石表面，复制犯罪现场和考古对象。
