Fusion of Image- and Inertial-Sensor Data for Navigation

Real-time image-aided inertial navigation is now feasible.

Amethod of real-time fusion of readout data from electronic inertial and image sensors for passive navigation has been developed. By “passive navigation” is meant navigation without the help of radar signals, Lidar signals, Global Positioning System (GPS) signals, or any other signals generated by on-board or external equipment. The concept of fusion of image- and inertial- sensor data for passive navigation is inspired by biological examples, including those of bees, migratory birds, and humans, all of which utilize inertial and imaging sensory modalities to pick out landmarks and navigate from landmark to landmark with relative ease. The present method is suitable for use in a variety of environments, including urban canyons and interiors of buildings, where GPS signals and other navigation signals are often unavailable or corrupted.
