| 摘 要： | 在卫星遥感中,需要校正因地球形状、地球自转、卫星轨道变化以及姿态偏离等因素造成的图像畸变。分析了卫星姿态偏离对AVHRR图像横向比例畸变和纵向扭曲畸变的影响,指出与地球曲率一样,卫星滚动也可使图像产生横向比例畸变,并提出了相应的校正模型。

| Abstract: | In remote sensing, it is necessary to correct the images for distortions due to Earth shape, Earth rotation, variations in satellite orbit and satellite attitude. In this paper, we analyze the effect of attitude deviation on the transverse proportion distortion and the portrait squirm distortion of AVHRR image, and point out that the rolling of satellite can bring image transverse proportion distortion just like the Earth shape's performance. We also develop a corresponding correction model. |
