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. |
