摘要
针对机载光电探测设备对位于地面背景下的运动目标检测虚警率高、实时性低的问题, 提出了一种基于航姿信息的运动目标检测算法。首先, 提取图像中的疑似目标点;然后利用疑似目标点在图像中的位置和载机的航姿信息解算得到目标在惯导坐标系下的位置信息, 并根据目标在惯导坐标系下的位置变化, 将目标分类为背景目标和备选目标;最后, 通过计算备选目标与背景目标的角度变化关系确定备选目标是否运动。通过半实物仿真的方式对算法进行验证。
Abstract
A moving object detection algorithm based on attitude information is proposed to solve the problem of high false alarm rate and low real-time for airborne electro-optic detection equipments for moving object detection in ground background. At first, the suspected target points in images are extracted. And then, the position of suspected target points in images and the attitude information of airborne equipments are used to calculate the position of the target in the inertial navigation coordinate system. According to the change of target position in the inertial navigation coordinate system, the suspected targets are divided into a background target and an alternative target. At last, whether the alternative target is moving or not is determined through calculating the angle relationship change of the alternative target and the background target. The algorithm is verified by the simulation.
