摘要
双面镜多元并扫成像方式在星载仪器中已得到越来越广泛的应用,但相应的遥感图像的预处理工作的重要性也日渐突出.文中从成像方式和仪器结构方面考虑,针对双面镜多元并扫成像方式提出了一套0级数据的几何方法,并对处理前后的图像质量进行了比较.结果表明,该校正方法可有效地改善图像的几何质量,校正效果良好.
As double-sided mirror multi-element scanning systems are now widely used in the spaceborne instruments, the preprocessing of the corresponding remote sensing images is becoming more and more important. In this paper, a geometric correction method for the original remote sensing image data obtained by a double-sided mirror multi-element scanning system is proposed. The image quality before and after correction is compared. The result has shown that this correction method can be used to effectively improve the geometric quality of the images ar.d has good correction effectiveness.
