摘要
以武汉市地理国情普查为例,针对标准时点核准下发影像数据处理存在的问题,构建了一套国产高分辨率卫星影像数据处理流程,提出了基于局部几何纠正的精度处理方法和基于影像融合的匀色处理方法。实验结果表明,该方法提高了核准影像的生产效率和质量,为国产高分辨率卫星影像的处理和应用奠定了坚实基础。
Taking the geographical conditions census of Wuhan for example,aiming at the problems of standard time point approval images data processing,this paper constructed a set of domestic high resolution satellite image data processing scheme,and proposed the accuracy processing method based on local geometric correction and the color balancing method based on image fusion.The experimental results show that the method can improve the quality and production efficiency of image data of standard time point approval,and lay a solid foundation for the processing and application of domestic high resolution satellite image.
