摘　　要：针对海空复杂背景下舰载光电跟踪仪的红外点目标检测跟踪问题,本文研究了一种基于三级流水管道的点目标轨迹检测与跟踪算法。该算法针对由光电跟踪仪实际拍摄的红外图像的二值分割图,利用第一、二级流水管道,完成对二值图像的二阶相关,实现更为有效的滤波除噪。利用第三级基于"或运算"的目标检测管道搜索目标点和进行目标点的准确定位,从而实现了从序列图像中可靠检测和跟踪点目标的目的。本文采用舰载光电跟踪仪实拍的红外图像,进行了实际的工程验证。结果说明,工程验证的结果与实验仿真结果相吻合,算法是可行的。Aiming at the detection and tracking of IR point targets in complicated sea-sky background, an algorithm for detecting and tracking targets based on the Triple Pipeline was studied. Making use of the first and the second pipelines, this algorithm could achieve effective filtering through quadratic correlation of binary IR images. The triple pipeline based on ＂OR＂ operation was used to search targets and mark their positions .The method discussed in the paper can detect and track targets reliably. In the practice of engineering, we used real IR images that were screened by opto-electronic tracker to validate the reliability of the algorithm. Experiment shows that practical results are accordance with emulational results, and the algorithm is feasible.
