中文摘要:在线阵传感器的航空摄影过程 中,飞机姿态变化会对成像造成影响,导致成像模糊。因 此根据航空投影的坐标变换方程,采用Monte Carlo算 法分析了曝光时间、稳定平台位置补偿残差以及角速度补偿残 差等参数对线阵相机成像质量的影响。结果表明,高性 能机载线阵相机必须配备高性能稳定平台;同时,灵敏度 高、曝光积分时间短的线阵探测器对于成像质量的提升 具有重要意义。

Influence of Stabilized Platform on Image Quality of Airborne Line Scan Camera
Abstract:In the aerial photography using linear array detectors, the variation of aircraft attitude may affect imaging and hence result in image blurring. According to the coordinate transformation formula of aviation projection, the Monte Carlo algorithm is used to analyze the influences of the factors such as exposure time, stabilized platform position residual compensation and angular velocity residual compensation on the imaging quality of linear array cameras. The results show that high performance airborne linear array cameras should be equipped with high performance stabilized platforms. Meanwhile, the linear array detectors with high sensitivity and short exposure time are of significance to the improvement of imaging quality.
