卫星数字化影像输出技术及其应用效果

Satellite Digital Image Output Tech nique and its Practical Use

随着数码成像技术的发展,卫星影像图制作过程中由于光学镜头产生的几何畸变、图像边缘模糊等图像失真问题得到根本解决,可显著提高卫星图像的清晰度和几何精度;而美国圣保利克公司生产的Light-Jet-5000RS型激光数码成像仪是目前国际上图像精度最高的图像输出设备,可获得较满意的卫星图像,本文扼要介绍了其成像原理、技术参数和实际应用效果。

Optical lens used for making satellite imaging picture may cause picture distortion errors due to geometrical aberration,blurred edges etc.,these problems can be basically solved b y using advanced new digital technology,consequently yielding satellite pi ctures with high sharpness and high p recision.Light -Jet -5000RS Laser Digital Imager made by St Paulic Co.,USA,is p resently the most precise picture im age output instrument in the world,and can offer satisfactory satellite pi cture;its imaging principle,techn ical specifications and results of practical use are outlined in this paper.
