Research on Quality Index System of Digital Aerial Photography Results

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. However, in the practical application, the production and quality inspection of digital aerial images have not had a complete norm to guide all the time. So in the subsequent application, image data appears lots of problems. Based on development situation at home and abroad and national existing regulation, generalize and establish a complete quality index system has a far-reaching significance in perfecting digitalization and informatization surveying and mapping technological system. The contents of quality inspection of aerial photography results are comprehensive, which include data quality,flying quality, the image quality and annex quality. From the perspective of productive practice, combined with practical experience of scanning digitalization production and a series of experiences of the quality inspection process of digital aerial images, the article focuses on the process to establish a complete quality index system.
