【摘要】 红外成像引信通过共享成像导引头实现前视探测 ,瞄准点识别是成像引信图像信息处理中的一个关键问题。首先对飞机红外图像进行预处理 ,然后进行中轴变换 ,提取飞机的骨架特征 ,并把瞄准点定义为特定邻域内骨架线分布最集中的节点 ,最后利用遗传算法确定最优瞄准点 ,结果证明文中的方法和算法是可行和有效的。更多还原

【Abstract】 The imaging IR fuze realizes forward detection by sharing the imaging seeker, recognition of aimpoint is a crucial issue in image information processing of fuze. We first pre process the infrared image of aircraft and then the medial axis transform is presented to extract the skeleton character of target. We define the aimpoint as a point in the skeleton, which has a maximum number of branches in a specific neighborhood. Finally, the best aimpoint through genetic algorithm was obtained. Some results show that the method proposed is feasible and effective.更多还原
