摘要
对天津地区无人机实验获取的单CCD四波段光谱成像仪数据进行分析,首先确定无人机遥感数据辐射/几何校正的方法,然后通过改变辐射/几何校正顺序,设计预处理研究流程,最后从图像的统计特征和纹理特征两方面入手,定量化地分析校正的先后顺序对处理结果的影响,并以此为依据建立新的无人机数据产品分级体系,为无人机遥感数据的处理流程优化及产品分类分级提供参考。
In this paper,we used four bands single-CCD imager data in Tianjin area as fundamental datum and processed them.Firstly,integrating data characteristics,the authors determined methods of radiometric and geometric correction.Secondly,technique flowchart was designed by changing the radiation and geometric correction order.Finally,the results obtained by different orders of radiometric calibration and geometric correction were quantitative analyzed from two aspects of statistical characteristics and texture features of images.On this basis,product rating system was built up.The experimental results showed that： For different underlying surface types of UAV remote sensing data,different geometric correction models have influence on the preprocessing results,but the difference can be ignored.This fact can provide a reference for the preprocessing of UAV remote sensing data and product rating.
