摘要
主要介绍利用SWDC-4航摄仪获取真彩色的数字航空影像,具有高分辨率、高成像质量的特点,并且可借助相关的后处理软件快速进行飞行漏洞的检查、图像处理、空三加密等。并通过实例分析了利用它进行城市基础空间信息获取的可行性,及成果的生成和精度评定,可在今后城市基础空间信息的获取中发挥重要的作用。
This paper describes the acquisition of true color aerial photograph with the characteristics of high resolution and high image quality using SWDC -4 aerial digital camera. It can quickly implement the inspection of aerial photographic gap, image processing, and aerial triangulation,etc, with the related postprocessing software. It analyzed the feasibility of urban fundamental spatial information acquisition, the generation of results, and accuracy assessment through examples. It can play an important role in the future of urban fundamental spatial information acquisition.
