这个小型企业创新研究第一期项目将研究为公路设计和维修的特殊领域开发一种创新的基于运动视频的摄影测量数据采集和处理系统的可行性。为了设计和维护运输系统，通常通过航空摄影、人工调查和劳动密集型数据处理等方式收集特定区域的三维数据。目前的航空摄影方法不能有效地收集从空中位置不容易看到的区域的数据。这些区域包括桥梁、岩面斜坡、河岸和隧道。该项目的目标是开发一种便携式，易于使用，基于运动视频的系统，该系统使用近距离地面摄影测量技术来精确建模未被航空方法覆盖的区域。除了运动摄像机外，数据采集系统的硬件将由全球定位系统（GPS）、编码器和笔记本电脑组成。该方法的一个新颖之处在于，通过使用数学模型，该系统将根据不同应用所需的精度进行定制。主要研究目标是开发获取准确摄像机位置和方位数据的方法，以及在视频图像之间自动识别和对应二维点的方法。新系统将在收集摄影测量、地面测量和地表描述数据方面节省大量人力和时间。CamSys公司在生产和销售用于获取摄影测量数据的自动化测量设备方面拥有丰富的经验，并且具有开发拟议新系统所需的独特能力。这个新系统的好处将包括创新的硬件软件方法来获取和处理视频数据，以产生用于评估桥梁和隧道状况的摄影测量和表面描述信息，以及对岩石表面斜坡和河岸进行建模。该系统将使设计和维护运输相关系统的过程更加高效和可靠。其他的商业应用还存在于交通、建筑、建筑、教育和娱乐等行业。

9560344 Lee This Small Business Innovation Research Phase I project will examine the feasibility of developing an innovative motion video-based Photogrammetry Data Acquisition and Processing System for special areas of highway design and maintenance. To design and maintain transportation systems, three-dimensional data on specific areas are collected usually by means of aerial photography, manual surveys, and labor intensive data processing. The current aerial photography methods cannot effectively collect data on areas that may not be seen readily from an aerial position. These areas include bridges, rock face slopes, river banks, and tunnels. The goal of this project is to develop a portable, easy-to-use, motion video based system that uses close-range terrestrial photogrammetry techniques to accurately model areas not covered by aerial methods. In addition to a motion video camera, the hardware of the data acquisition system will consist of a Global Positioning System (GPS), encoders, and a laptop computer. A novel feature of the method is that the system will be tailored to the accuracy desired for different applications through the use of a mathematical model. The main research objectives focus on developing methods to obtain accurate camera position and orientation data, and to automatically identify and correspond 2D points between video images. The new system will offer significant labor and time savings in gathering photogrammetry, ground survey, and surface description data. CamSys, Inc. has extensive experience in producing and marketing automated measurement equipment for acquiring photogrammetry data, and has distinct capabilities needed to develop the proposed new system. Benefits of this new system will include innovative hardware-software methods to acquire and process video data to produce photogrammetry and surface description information for assessing the condition of bridges and tunnels, and modeling rock face slopes and river banks. The system will make the process of designing and maintaining transportation related systems more efficient and reliable. Additional commercial applications exist in industries such as transportation, construction, architecture, education, and entertainment.
