Separated Image Analysis Method based on Monocular Vision

运载火箭分离安全性是飞行安全性的关键特性,获取火箭飞行过程中助推、各子级及星箭分离时刻及分离后的速度、加速度及距离变化曲线是分离安全性分析的核心内容。针对此问题,根据箭载摄像头天基视频,提出了一种基于单目视觉图像的运载火箭分离过程分析方法,通过图像序列的运动视差,变换并求解得到分离目标与摄像装置在特定序列内的距离变化曲线;同时基于此建立了面向分离安全性分析的一种靶标设计方法,并对飞行过程分离后靶标图像使用本方法进行了分析,进一步验证了利用单目视觉图像获得分离关键参数的可行性。
