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.

9560344 Lee这个小型企业创新研究第一阶段项目将研究为公路设计和维护的特殊领域开发基于运动视频的创新摄影测量数据采集和处理系统的可行性。为了设计和维护交通系统，通常通过航空摄影、人工测量和劳动密集型数据处理来收集特定地区的三维数据。目前的航空摄影方法不能有效地收集从空中位置可能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的、易于使用的、基于运动视频的系统，该系统使用近距离陆地摄影测量技术来准确地模拟航空方法未覆盖的区域。除了运动摄像机，数据采集系统的硬件将包括全球定位系统(GPS)、编码器和笔记本电脑。该方法的一个新特点是，通过使用数学模型，系统将被定制为不同应用所需的精度。主要的研究目标是开发获取准确的摄像机位置和方向数据的方法，以及自动识别和对应视频图像之间的二维点。新系统将在收集摄影测量、地面测量和表面描述数据方面节省大量劳动力和时间。CamSys公司在生产和销售用于获取摄影测量数据的自动测量设备方面拥有丰富的经验，并具有开发拟议的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和软件方法，以获取和处理视频数据，以产生摄影测量和地面描述信息，用于评估桥梁和隧道的状况，以及建立岩面斜坡和河岸的模型。该系统将使设计和维护与交通相关的系统的过程更加高效和可靠。其他商业应用还存在于交通、建筑、建筑、教育和娱乐等行业。
