摘　　要：提出了一种面向多波束声呐数据特定区域的可视化截取算法。在数据格网化基础上,实现数据的可视化;然后通过数据分块算法构建多边形截取模型,实现多波束声呐特定区域数据的可视化快速截取,并用实测数据进行了验证。Due to the large quantities of the multi-beam sonar data,the data processing can be very time-consuming with the conventional method.To efficiently analyze the specific targets and recover the ground objects deleted by mistake,a fast extraction method of multi-beam sonar data is necessary,which can extract data in a specific area from the massive data.An extraction method of multi-beam sonar data based on visualization is proposed to carry out multi-beam data processing.Firstly,multi-beam sonar data are visualized by gridding transformation.Then,the extraction model is built to extracting the visualized data,which is based on the algorithm of data segmentation.Finally,the multi-beam bathymetric data are used to serve as the reference to verify the validity of the proposed method.
