摘要
由于航空遥感器要求的分辨率愈来愈高,因此需要更为精确的像移补偿模型。本文针对拍照时飞机姿态角变化在遥感器像面处所引起的姿态像移,运用光线矢量与坐标系旋转相结合的方法建立遥感器姿态变化过程的数学模型。通过坐标系的旋转表示姿态的变化,根据遥感器姿态变化前后像面上各离散点的光线矢量之差,获得遥感器的姿态像移在像面上的大小与分布特征。运用该像移模型对遥感器姿态像移进行分析,提出减小姿态像移的工程措施。
As the resolving power of aerial remoto sensor is demanded to be highier, the more precise image motion compensation model is needed. This aritele in view of the gesture image motion which causes by the altering airplane gesture angles including pitching angle, yawing angel and rolling angle, unifies the light vetor and coordinate system revolving methods to establish a mathematical model of the remote sensor＇s gesture change process ,in which it is supposed that the rotation of the coordinate system is equal to the change of the gesture angle. The magnitude and the direction of the remote sensor＇s gesture image motion can be obtaining in the image plane by calculating the light vetor drift of each diserese piont in the image plane. This method can be used in image motion compensation system.
