Method for inspection of frame digital aerial photographic quality

Abstract

At present,the aerial photographic quality inspection still uses the traditional method to check the digital frame images' quality,which prints the digital images on paper first and then checks them manually. The method greatly limits the advantages of digital aerial photography. This paper presents a fully digital aerial photographic quality inspection method,whose whole process is fully completed on computer. Firstly,index images are used to complete the image quality inspection,Then the aerial photography flight quality inspection software and airborne POS( position and orientation system) data are employed to check such quality factors as overlap,swing angle,strip deformation,and flying height,Finally,relevant documentation is collated and prepared according to the results. In order to verify the reliability and scientificalness of this method,the authors selected the manual quality inspection results of Hengyang area in Hunan Province to make comparison and analysis. The results show that this method can actually reflect the flight quality of aerial photography,is in good consistency with manual results,and has some other advantages such as simple operation,high efficiency and low cost.
