| 摘 要： | 在景象匹配定位系统中，采用下视的方式获得地面图像。由于受飞行载体空间的限制，有时需要采取航向随动、滚动俯仰捷联方案。这样获取的地面图像只是纵轴与地理坐标保持一致，存在着飞行载体的俯仰、滚动等姿态导致的畸变，需对图像进行姿态畸变校正。这里给出航向随动控制调整角α与姿态角(φ，θ，γ)的数学关系以及姿态畸变校正的基本公式。

| Abstract: | In the scene matching system, the axis of camera is looking-down. For the limit of the interspace the camera is in strap-down way with carrier in pitch and the rolling direction. In this way, only the y-axis of the ground image accords with geography coordinate, and there is distortion from pitch and rolling attitude. Before images matching, correction is needed. Mathematical relation of adjustment angle α of course tracking control and attitudes (φ,,γ) and formulae of correction of the distortion are given. |
