摘　　要：目标提取的视频距离估算方法在舰船动平台应用过程中,由于舰船摇摆导致获取目标像素高度不稳定,从而获取的目标估算距离不稳定,针对这个问题提出了舰载光电侦察设备视频测距实时修正方法。该方法以修正后的像素高度替代视频距离估算公式的原始像高,得到了稳定的视频估算距离。仿真实验结果表明,采用此修正方法很好地解决了由于船体摇摆导致的估算距离不准问题,使视频距离估算方法在舰载光电侦察设备中得到了很好的应用,提高了舰载光电侦察设备的整体性能。In order to solve the problem that the height of the target pixel was unstable due to the sway of the ship when the video distance estimation method based on the target extraction was applied,a real-time correction method of the video distance of the shipboard photoelectric reconnaissance equipment was proposed.In this method,the original pixel height of the video distance estimation formula was replaced by the modified pixel height,and a stable video estimation distance was obtained.The simulation results showed that this method could solve the problem of inaccurate estimation distance caused by the sway of the ship,which made the video distance estimation method well applied in the shipborne photoelectric reconnaissance equipment,and improved the overall performance of the shipborne photoelectric reconnaissance equipment.
