The invention provides a ship monitoring intrusion detection method based on mode matching. The method comprises the following steps: obtaining a structural mode sub-vector between two images according to a brightness difference, a contrast difference and a gamma difference; calculating a mode distance by taking the structural mode sub-vector as a feature vector; and according to the mode distance, an optimal decision threshold is obtained through an optimization method, so that whether an invader exists or not is judged. According to the technical scheme, the scene is kept static for a long time under the condition of no invasion, a plurality of observation images can be recorded and stored in the database under the conditions of different illumination conditions, different meteorological conditions and the like, and the mode distance between the newest observation image and the historical image in the database is calculated in the later period to judge whether an invader exists or not.

    本发明提供一种基于模式匹配的船舶监控入侵检测方法。本发明方法,包括:根据亮度差异、对比度差异和伽马差异,得到两图像之间的结构模式子向量;将结构模式子向量作为特征向量,计算模式距离;根据模式距离,通过优化方法得出最佳决策阈值,从而判断是否存在入侵物。本发明的技术方案因无入侵情况下场景长时间保持静态,可以在不同光照条件、不同气象条件等情况下记录若干观测图像并存入数据库,并在后期计算最新观测与数据库中历史图像的模式距离判定是否存在入侵物。
