This book was released on 2014-08-20 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given a known aircraft location, a set of camera calibration parameters can be used to correlate features in an image with ground locations. Previously, these calibration parameters were obtained during preflight with a lengthy calibration process. A method to automate this calibration using images taken with an aircraft mounted camera and position and attitude data is developed. This thesis seeks to determine a partial set of circumstances that affect the accuracy of the calibration results through simulation and experimental flight test. A software simulator is developed in which to test an array of aircraft maneuvers, camera orientations, and noise injection. The simulator uses a realistic aircraft model in order to accurately derive the inputs to the calibration routine. Features are generated and used to create a set of fictitious images to feed the calibration routine. Results from the simulation are used to prepare test points for an experiment flight test conducted to validate the calibration algorithm and the simulator. Real world flight test methodology and results are discussed. Images of the ground along with precise aircraft navigation and time data were gathered and processed for several representative aircraft maneuvers using two camera orientations. Only the straight and level maneuver is found to be detrimental to accurate calibration results. Feature measurement noise is found to be highly detrimental to parameter estimation while navigation noise has little affect. These results are validated with both simulated and experimental results.

Available in PDF, EPUB and Kindle. Book excerpt: As the need for geographical data rapidly expands in the 21st century, so too do applications of small-format aerial photography for a wide range of scientific, commercial and governmental purposes. Small-format Aerial Photography (SFAP) presents basic and advanced principles and techniques with an emphasis on digital cameras. Unmanned platforms are described in considerable detail, including kites, helium and hot-air blimps, model airplanes, and paragliders. Several case studies, primarily drawn from the geosciences, are presented to demonstrate how SFAP is actually used in various applications. Many of these integrate SFAP with ground-based investigations as well as conventional large-format aerial photography, satellite imagery, and other kinds of geographic information. - Full-color photographs throughout - Case studies from around the globe - Techniques presented allow for image resolution impossible to match via traditional aerial photography or satellite datasets - Glossary clarifies key terms
