Abstract: An imaging platform minimizes image distortion when there is relative motion of the imaging platform with respect to the scene being imaged where the imaging platform may be particularly susceptible to distortion when it is configured with a wide field of view or high angular rate of movement, or when performing long-stares at a given scene (e.g., for nighttime and low-light imaging.) Distortion correction may be performed by predicting distortion due to the relative motion of the imaging platform, determining optical transformations to prevent the distortion, dynamically adjusting the optics of the imaging platform during exposure, and performing digital image correction.

Abstract translation: 当成像平台相对于正在成像的场景存在相对运动时，成像平台在被配置为具有宽视野或高角速度运动时可能特别容易受到失真的影响，成像平台使图像失真最小化，或 当在给定的场景（例如，夜间和低光成像时）进行长时间观察时，可以通过预测由于成像平台的相对运动引起的失真来进行失真校正，确定光学变换以防止失真，动态地调整 曝光期间成像平台的光学元件，以及进行数字图像校正。
