This Small Business Innovation Research (SBIR)Phase I research proposal addresses synergistic integration of navigation and environmental sensing instruments on manned or autonomous ground or air vehicles to both improve information registration accuracy and reduce costs of hardware. This will enable use of low cost Micro Electro-Mechanical Systems (MEMS) Inertial Measurement Units (IMU) and will relax export requirements for remote sensing hardware heretofore based upon military-derived IMU components. This research will address the use of a digital camera and MEMS IMU that are tightly integrated in a novel manner so that navigation will occur within a coordinate frame that is fixed within the surrounding scene as observed by the digital remote sensing camera. Remote Sensing involves sensing physical properties of terrestrial objects from a distance and registering the sensed information into a geodetic reference frame. Such registration is critical for merging related data sources and for change detection from sequential data collects. Direct Geo-registration (DG) involves performing registration without prior knowledge of geodetic survey information collected from the vicinity of the sensed feature. Precision navigation using inertial navigation and GPS is a fundamental aspect of modern approaches to DG. Detection, tracking and subsequent re-acquisition of sensed features can be used as additional aides for improved navigation.

这项小型企业创新研究（SBIR）第一阶段研究提案旨在将导航和环境传感仪器协同集成到载人或自主地面或空中车辆上，以提高信息注册的准确性并降低硬件成本。这将使得能够使用低成本的微机电系统惯性测量单元，并将放宽对迄今为止基于军用惯性测量单元部件的遥感硬件的出口要求。这项研究将解决使用的数码相机和MEMS惯性测量单元是紧密集成在一个新的方式，使导航将发生在一个坐标系内，是固定在周围的场景观察到的数码遥感相机。遥感涉及从远处感测地球物体的物理特性，并将感测到的信息记录到大地测量参照系中。这种注册对于合并相关数据源和从顺序数据收集中进行更改检测至关重要。直接地理配准（DG）是指在没有从感测特征附近收集的大地测量信息的先验知识的情况下执行配准。使用惯性导航和GPS的精确导航是现代DG方法的一个基本方面。检测、跟踪和随后的重新获取感测特征可以用作改进导航的附加辅助。
