    摘要:

    针对基于图像的电子稳像不能适应机载光电系统的复杂应用环境,包括载机机动、光电系统调转、目标场景不确定等因素造成不能准确获取抖动量从而难以补偿等问题。本文采用陀螺与图像处理相结合的电子稳像技术,基于陀螺数据估计出稳定平台的抖动像素,通过图像序列帧间实时像素补偿,消除图像抖动。在不需要额外增加硬件的条件下,提高了机载光电系统视频图像的稳定性。该方法目前已在某型飞行员夜视系统上进行了验证。结果表明,在原有硬件条件下,该方法可显著提高夜视系统图像的稳定性。

    Abstract:

    In view of theproblem that image based electronic image stabilization cannot adapt to the complex application environment of airborne photoelectric system,including the factors as aircraft maneuvering,photoelectric system rotation and the uncertainty of target scene,the accurately obtainit difficult to compensate.In this paper,the electronic image stabilization technology combining gyro and image processing isd to estimate the jitter pixels of platform,and the image jitter is eliminated by real time pixel compensationbetween image sequence frames.The stability of the video image of the airborne photoelectric systemimproved without additional hardware.method has been verified .The results show that this method can significantly improve the image stability of the night vision system under the original hardware conditions.
