Research on automatic inspection methods of flight quality of digital aerial photography results

Abstract

Aerial photogrammetry is one of the main methods obtaining geospatial information. After entering the 21st century, aerial photogrammetry technology has fully entered the digital age, and the quality of digital aerial photography results will directly affect the quality and accuracy of results of surveying and mapping.Therefore, it is necessary to inspect the quality of digital aerial photography results. In the process of digital aerial photography, flight quality directly affects the quality of the results. It is of great importance to make its flight quality inspection. Based on the analysis of flight quality index of the results of digital aerial photography and domestic and international current situation of quality inspection technology of aerial photography results, the author has researched and has posed inspection index and automatic inspection methods of flight quality of the results of digital aerial photography; they can be applied to check index, such as longitudinal overlapping degree, lateral overlapping degree, rotation angle, andthe curvature of airline of images, to realize automatic quality inspection of flight quality of the results of digital aerial photography. © 2012 IFIP Federation for Information Processing.
