Abstract

Multi-mode Airborne Digital Camera System (MADC) is a novel airborne digital camera developed by Institute of Remote Sensing Applications of Chinese Academy of Sciences. The image acquisition and processing of MADC system and its application in the mapping and application of city ortho-image are introduced in the paper. The Jining city in Shandong province was taken as an example for the application and analysis. Sever primary data processing algorithms correlating of MADC system have been introduced in the paper, mainly involved: the algorithm of camera lens distortion and proofreading method, the algorithm which efftcts the image because of terrain undulation and the algorithm of ortho-image generation. The work flow is proposed for image processing and ortho-image generation using MADC image data. At the end, some suggestions are put forward for improving the performance of MADC system and increasing its application in city remote sensing.
多模机载数码相机城市正射影的测绘与应用
多模机载数码相机系统(MADC)是中国科学院遥感应用研究所研制的一种新型机载数码相机。本文介绍了MADC系统的图像采集和处理,以及MADC系统在城市正射影像测绘和应用中的应用。以山东省济宁市为例进行了应用分析。本文介绍了MADC系统相关的几种主要数据处理算法,主要包括:摄像机镜头畸变校正算法、地形起伏对图像的影响算法和正射影像生成算法。提出了利用MADC图像数据进行图像处理和正射影生成的工作流程。最后,对提高MADC系统的性能,扩大其在城市遥感中的应用提出了建议。
