摘要: 地形辐射校正对获取准确的地表定量遥感精度意义重大。针对传统地形辐射校正模型不适用于高分辨率遥感影像的问题,提出了一种基于辐射传输模型,同时严控误差源的地形辐射校正方法,以资源三号01星高分辨率全色及多光谱遥感影像为例进行相关实验,实现对高分辨率遥感影像的地形辐射校正,并进行了主客观分析与评价。分析结果表明:本文提出的地形辐射校正模型和方法,能有效解决全色遥感影像在绝对辐射定标系数缺失情况下校正效果差以及如何保持高分辨率遥感影像细节等难点,较传统方法更适用于高分辨率遥感影像。

Abstract: Topographic correction is critical to the accuracy of the earth's surface quantitative remote sensing. Traditional topographic corrective models are not so suitable for high-resolution remote sensing images. In order to address the problem, this paper proposes a topographic correction method based on radiation transfer model and strict control over error sources. High-resolution panchromatic and multispectral images of ZY3-01 satellite were taken as examples to conduct relevant experiments, and the topographic correction of high-resolution remote sensing images was realized with subjective and objective analysis and evaluation. The analysis results show that the problems of poor correction effect without absolute radiometric calibration coefficient in topographic correction of panchromatic remote sensing images can be effectively solved and the detail of high-resolution remote sensing images can also be maintained by the proposed model and method. So it is more suitable for high-resolution remote sensing images than traditional methods.

Key words: high-resolution remote sensing image, topographic correction, radiation transfer, absolute radiometric calibration coefficient, digital surface model (DSM)
