基于国产卫星的数字正射影像图生产优化研究

Research on the Production Optimization of Digital Orthophoto Maps Based on Domestic Satellites

国产卫星影像获取能力越来越强,数字正射影像图可以广泛应用于自然资源管理、城市建设、生态环境等领域。以“吉林一号”卫星影像数据为例,采用吉威、沃韦航片卫片图像智能优化应用软件进行数据处理,针对融合纠正步骤,进行先融合后纠正与先纠正后融合的对比差异,并通过多种图像增强方式,探索一种精度符合要求、成果质量较好、生产效率较高的生产方法,指导生产更高效。

The ability of domestic satellites to acquire images is becoming stronger and stronger,and digital orthophoto maps can be widely used in natural resource management,urban construction,the ecological environment and other fields.Taking"Jilin-1"satellite image data as an example,this paper processes data by using the intelligent optimization and application software of Geoway and Worldview aerial photo and satellite photo images,compares the difference between first fusion and then correction and first correction and then fusion for the fusion correction step,and explores a production method with satisfactory accuracy,good achievement quality and high production efficiency through a variety of image enhancement methods to guide production to be more efficient.
