Abstract: Since the navigation equipment for inland river ships, such as radar, radio reception hedge etc, as target information can not be accurately obtained in various heavy climate condition, it can not satisfy the requirement of reliable ship collision avoidance. This paper employs infrared ship target detection tracking technique based on MFFK fractal characteristics and Mean-Shift combined algorithm. The real-time motion infrared video is acquired along the ship direction and on both sides. The single frame picture is extracted to separate suspicious man-made objects from the background environment via MFFK parameter. Mean Shift method is employed for target tracking. The experimental?results show that all kinds of changes and situation like scene movement target?crisscross?can be?dealt?by?this?algorithm.?The algorithm is?robust.

摘要： 当前内河船舶配备的导航设备，如雷达、无线电信号接收避险等，无法在各种恶劣气候条件下准确获取目标的信息，不能满足可靠的船-船、船-桥避碰要求。采用基于MFFK分形特征与Mean-Shift方法相结合的红外船舶目标检测跟踪技术，在其运动过程中实时采集来自船运动前方以及两侧环境情况的视频文件，同时将其转化为单帧的实时红外图像，通过MFFK参数将环境与可疑人造目标分离开，然后采用基于Mean-Shift的目标跟踪技术进行目标定位，跟踪，通过对连续红外图像高速比对，在其运动轨迹发生变化可能产生事故之前发出警报。实验结果表明，该算法能够应付场景的各种变化以及多运动船舶目标交错遮挡等情形，算法具有鲁棒性。
