摘要
介绍了尾流图像数字化处理工作原理及方法.用MATLAB软件对船舶时速分别为30 km/h和40 km/h的两幅尾流图像进行了灰度变换、滤波、Canny边缘化、二值变换、直方图变换等,并对实验结果进行了初步分析,得到了船舶航速影响尾流边缘夹角、边缘弯曲度及直方图峰值变化.研究结果为尾流图像进入信息化系统提供了基础.
Abstract
The working principles and methods of wake images digital processing system were introduced. The gray-scale transformation, filtering, Canny marginalization, binary transformation and histogram transformation of two wake flow images were carried on, the speed of which are 30 km/h and 40 km/h respectively, using MATLAB software, experimental results were analyzed,and the speed of the ship wake edge angle, edge curvature and histogram peak change were obtained. The research results provide a basis for wave images entering the informationization system.
