| 摘 要： | 为解决由舰船动力装置、武器发射以及海浪撞击等震动引起的光电系统图像的高频抖动，研究了舰载成像系统的稳像软平台技术。该技术以计算机算法代替硬件平台，实现视频序列稳定。同时，针对光流场求解不能满足实时性要求的问题，提出了矢量块分割记忆优化算法。实船试验表明，软平台技术对于成像系统具有良好的稳定性和观测精度；与基于高斯金字塔多分辨率分解的光流场计算方法相比，新算法可以节省1／4以上的计算时间，具有重要的工程应用价值。

| Abstract: | A new image stabilization technology based on soft-platform was studied. By replacing hardplatform with computer algorithm, it can eliminate the high frequency image jitter of shipborne optoelectronic-imaging system. To overcome the shortcoming of optical flow estimation in real time, a new algorithm based on optimizing vector-block segmenting was provided. Experimental results show that soft-platform possesses good stability and observing precision for imaging system, and based on the comparison between optical flow estimation of Gaussian pyramid method and the algorithm in the paper, the new algorithm can reduce the working time for more than 25 %. |
