摘要
因卫星影像采集时间、成像条件、传感器类型不同等原因,各景影像之间往往存在较大的色彩差异,若不进行处理,在进行大范围影像镶嵌拼接时,接边处会存在明显的接边线,严重影响视觉效果及后期的使用分析。针对此问题,本文在研究分析WorldView Pro影像色彩平衡原理的基础上,总结出一套适用于多源卫星影像色彩平衡的技术方法,通过实验数据测试以及实际工程应用证明,该技术流程满足实际生产要求,适用于大范围多源卫星影像的色彩平衡处理。
Due to satellite image acquisition time,imaging conditions,different sensor types,etc.,there are often large color differences between scene images.Without processing,when large-scale image mosaic is stitched,there will be obvious edges,which seriously affects the visual effect.Aiming at this problem,based on the research and analysis of the principle of image color balance of WorldView Pro,this paper summarized a set of technical methods applicable to multi-source satellite image color balance.Through experimental data testing and practical engineering application verification,this technical process can meet actual production requirements,suitable for color balance processing of large-scale multi-source satellite images.
