| 摘 要： | 与星载MSS(或TM)相比,AMSS成像具有独特的特点,其为行扫描方式,扫描视场角大,飞机飞行高度低,运动变化大,姿态稳定性差。因此,各种成像干扰因素对AMSS图像的影响更为严重,引起的图像几何畸变更为复杂,校正不仅非常困难,而且仿卫星扫描图像几何模式得不到正确有效的校正效果。本文详细地定量分析了各种因素对AMSS图像几何特性的影响,希望有助于AMSS图像几何畸变校正方法的研究。

| Abstract: | Comparing with satellite borne MSSor TM, Airborne Multispectral Scanner (AMSS)has unique characteristics: Line-scanning rotating mirror type with large field of view, lower flying altitude and poor stability of movement and orientation of the platform. Therefore, the effects of various disturbing factors on AMSSimage are severe and geometric distortions caused by these factors in AMSSimages are more complex. Geometric correcting rot only is difficult, but also accurate and effective geometric correction cann’t be done according to imaging geometric mode of satellite borne MSSor TM. This paper quantitatively analyzes effects of various factors on geometric characteristics of AMSSimage in details, it is helpful to develop the method for correction of geometric distortions in AMSSimage. |
