摘　　要：本文依据船舶尾流产生的感应磁场模型,以新巴拿马船型为例,在一定的航行条件下,应用MATLAB软件,得到了尾流感应磁场仿真图像和灰度图像,并对此图像进行了直方图处理和边缘检测处理。通过对该图像的处理分析,得到如下结论:随着船舶航行距离增加,感应磁场逐渐减小,同时呈现出周期性的变化,感应磁场的范围逐渐变宽。用Canny算子检测尾流感应磁场仿真图像能够检测到清晰的弱边缘,不容易受到噪声干扰。Based on the induced magnetic field model generated by the wake of the ship,the new Panamanian ship type was taken as an example.Under certain navigation conditions,the MATLAB software was used to obtain the wake-induced magnetic field simulation image and gray image,and the image was histogram,processing and edge de?tection processing.Through processing and analysis of the image,the following conclusions were drawn:with the in?crease of the ship's navigation distance,the induced magnetic field decreased gradually,while showing periodic chang?es,and the range of the induced magnetic field becomed wider gradually.Using the Canny operator to detect the wakeinduced magnetic field simulation image can detect clear weak edges and is not susceptible to noise interference.
