摘　　要：为了获取完整清晰海底地貌边界,为海洋工程建设与环境监测等提供科学依据,设计多波束测深和图像分割的海底地貌边界提取方法。采用多波束测深系统采集海底地貌测深数据,利用数据生成海底地貌深度图像,经灰度化、滤波及增强处理此深度图像后,获取高质量海底地貌灰度图像,结合全局阈值分割方法分割此灰度图像,获得图像内海底地貌边界部分,实现海底地貌边界提取。结果表明,该方法根据测深数据生成的图像质量好,对比度高,暗处细节清晰,提取的海底地貌边界清晰、完整,具有较高的实际应用价值。In order to obtain complete and clear submarine geomorphic boundary and provide scientific basis for marine engineering construction and environmental monitoring,a method for extracting submarine geomorphic boundary using multi beam bathymetry and image segmentation is designed.The multi beam bathymetric system is used to collect the bathymetric data of submarine geomorphology,and the data is used to generate the depth image of submarine geomorphology.After the depth image is grayed,filtered and enhanced,the high-quality grayscale image of submarine geomorphology is obtained.The grayscale image is segmented with the global threshold segmentation method to obtain the submarine geomorphology boundary part in the image,and the submarine geomorphology boundary is extracted.The results show that the image generated by the method based on the bathymetric data has good quality,high contrast,clear details in dark places,and clear and complete submarine geomorphic boundaries,which has high practical application value.
