辐射产品的卫星影像内部畸变几何标定
|
摘要
针对卫星发射以后,由于外部太空环境的变化和相机光学系统的径向畸变导致卫星成像影像的外部误差和内部畸变,须对光学遥感相机长期周期性地进行几何标定消除卫星影像系统误差和相机指向角误差提高卫星影像几何定位精度的问题,该文从简单易行的角度出发,基于相机的CCD固定偏差原理构建一种新型的模型或内标定算法消除影像的内部畸变,以经过畸变改正的卫星影像辐射产品为参考控制,采用亚像素匹配法构建内部畸变模型修正卫星遥感影像的内部畸变,并分别以不同侧摆角和影像行数的SJ9A和ZY3为实验和参考控制数据构建和验证新型标定模型的有效性和实用性。
Aiming at the problem that after the satellite is launched geometric calibration need to be implemented for inner distortion of satellite imaging camera in periodical time in order to improve the geometry positioning accuracy of satellite imagery since outer space environment variety and camera optical system radial distortion result in external errors and internal distortion of satellite imagery.A new model or method of operation was studied.In this paper,internal distortion model was built by sub-pixel matching method between satellite imagery products and radiometric correction product for the reference radiation control in order to correct the inner distortion of satellite remote sensing imagery,and SJ9 Aand ZY3 satellite imagery at different side-angles and lines were applied to construct inner distortion model to verify the validity and practicality of the new calibration model.
