摘要： A method and system for navigation of an unmanned aerial vehicle (UAV) in an urban environment are provided. The method comprises capturing a first set of Global Positioning System (GPS)-tagged images in an initial fly-over of the urban environment at a first altitude, with each of the GPS-tagged images being related to respective GPS-aided positions. The captured GPS-tagged images are stitched together into an image mosaic using the GPS-aided positions. A second set of images is captured in a subsequent fly-over of the urban environment at a second altitude that is lower than the first altitude. Image features from the second set of images are matched with image features from the image mosaic during the subsequent fly-over. A current position of the UAV relative to the GPS-aided positions is calculated based on the matched image features from the second set of images and the image mosaic.

摘要： A pipeline inspection and defect mapping system includes a pig having an inertial measurement unit and a pipeline inspection unit for recording pig location and defect detection events, each record time-stamped by a highly precise onboard clock. The system also includes several magloggers at precisely known locations along the pipeline, each containing a fluxgate magnetometer for detecting the passage of the pig along the pipeline and further containing a highly precise clock synchronized with the clock in the pig. The locations of the various magloggers are known in a north/east/down coordinate system through a differential global positioning satellite process. Finally, a postprocessing off-line computer system receives downloaded maglogger, inertial measurement, and odometer data and through the use of several Kalman filters, derives the location of the detected defects in the north/east/down coordinate frame. Consequently, a task of identifying sites for repair activity is much simplified.

摘要： An elongated inertial measurement unit having a plurality of gyros, none of which is aligned with the cardinal longitudinal axis of the elongated housing. At least one gyro has its input sensing axis aligned at an angle between 35 and 55 degrees, preferably at 45 degrees, relative to the cardinal longitudinal axis. This results in effective dithering by each of the enclosed gyros. All of the gyros are situated such that the centers of their masses or configurations are aligned with or approximately located in a row along the longitudinal axis of the elongated housing. The housing may be of various cross-sectional shapes, but the preferred shape of such housing is a right circular cylinder.

摘要： A method and system for navigation of one or more unmanned aerial vehicles in an urban environment is provided. The method comprises flying at least one Global Positioning System (GPS)-aided unmanned aerial vehicle at a first altitude over an urban environment, and flying at least one GPS-denied unmanned aerial vehicle at a second altitude over the urban environment that is lower than the first altitude. The unmanned aerial vehicles are in operative communication with each other so that images can be transmitted therebetween. A first set of images from the GPS-aided unmanned aerial vehicle is captured, and a second set of images from the GPS-denied unmanned aerial vehicle is also captured. Image features from the second set of images are then matched with corresponding image features from the first set of images. A current position of the GPS-denied unmanned aerial vehicle is calculated based on the matched image features from the first and second sets of images.
