Part 1: Simulation, Optimization, Monitoring and Control TechnologyInternational audienceAerial 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, image quality directly affects the quality of the results. It is of great importance to make its image quality inspection. Based on the analysis of image 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 put forward the index system which consists of subjective evaluation index and objective evaluation index. Based on objective evaluation index which includes the maximal displacement of image points, image definition, uniform degree of image contrast and brightness and image integral color performance, the author has researched automatic inspection methods of image quality of the results of digital aerial photography, and has realized automatic quality inspection of image quality of the results of digital aerial photography
