The invention relates to an aviation airborne photoelectric load image motion compensation system and method, in particular to a continuous circumferential scanning linear motion image motion compensation system and method, which are used for solving the problems that the existing moving target surface image motion compensation system adopts a linear driving compensation form, so that the volume structure is large, the requirements of high motion precision and high compensation frequency cannot be met, and the cost is low. And therefore, the high-frequency image motion compensation effect is difficult to realize. The continuous circumferential scanning linear motion image motion compensation system comprises a camera main control system, a driving mechanism, an elastic assembly, a base, a target surface bracket and a camera target surface, wherein the driving mechanism comprises a driving device, an eccentric reducing rotating wheel and an encoder; the driving device unidirectionally drives the eccentric variable-diameter rotating wheel to rotate, and the eccentric variable-diameter rotating wheel rotates at a high speed to drive the camera target surface to linearly move at a constant speed so as to realize image motion compensation. Meanwhile, the invention provides a continuous circumferential scanning linear motion image motion compensation method.

    本发明涉及航空机载光电载荷像移补偿系统及方法,具体涉及一种连续周扫线性运动像移补偿系统及方法,用于解决现有动靶面像移补偿系统采用直线驱动的补偿形式,导致体积结构较大,并且无法满足高运动精度和高补偿频率的要求,从而难以实现高频像移补偿效果的不足之处。该连续周扫线性运动像移补偿系统包括相机主控系统、驱动机构、弹性组件、底座、靶面支架和相机靶面,其中驱动机构包括驱动装置、偏心变径旋转轮和编码器;驱动装置单向驱动偏心变径旋转轮旋转,通过偏心变径旋转轮高速旋转带动相机靶面线性匀速运动来实现像移补偿。同时,本发明提供一种连续周扫线性运动像移补偿方法。
