摘要
常规的图像处理技术生成的水下地形图存在对比度误差,导致选择的航行线路不是最优,因此研究新式图像处理技术在航海导航系统中的应用。该技术通过灰度阈值法去除图像背景,实现对图像的二值化处理。识别单连通区域,利用边缘检测算子计算偏差,根据得出目标物的边界值,分割二值图像。提取分割图像中水面上与水面下的地形特征,设置该海域图像的对比度,以此反映此处地形的起伏状态,实现图像处理技术在航海导航系统中的应用。实验结果表明,与常规图像处理技术相比,本文导航系统生成的图像对比度更高,反映出的海域地形更加精准。应用这一技术,航海导航系统生成的路径最优。
Conventional image processing technology produces underwater topographic map with contrast error,which leads to the selection of navigation route is not optimal.Therefore,the application of new image processing technology in navigation navigation system is studied.The image background is removed by gray threshold method,and the binary processing of image is realized.The simply connected region is identified,the deviation is calculated by the edge detection operator,and the binary image is segmented according to the boundary value of the object.The terrain features on the water surface and below the water surface in the segmented image are extracted,and the contrast of the images of the sea area is set to reflect the fluctuation of the terrain,so as to realize the application of image processing technology in navigation system.The experimental results show that compared with the conventional image processing technology,the images generated by the navigation system under the studied technology have higher contrast and reflect more accurate marine terrain.It can be seen that the navigation navigation system generates the optimal path under the application of this technology.
