【摘要】：多波束水体影像近年来得到了广泛的应用,但由于缺少格式标准,各多波束厂商所支持的格式各不相同,给进一步的数据处理带来了一定的困难。基于Matlab平台,通过对ALL格式多波束测深数据文件与WCD格式多波束水体影像文件进行了详细的解析,并且研究了最近邻插值、改进最近邻插值、二维线性插值与三次多项式插值等多种算法,实现了多波束水体影像的回放显示与水体异常提取,并且实现了回放速度的控制,极大地提高了资料处理效率。
[Abstract]:Multi-beam water image has been widely used in recent years, but due to the lack of format standard, the format supported by the multi-beam manufacturers is different, which brings some difficulties to the further data processing. By analyzing the ALL format multi-beam bathymetric data file and the WCD multi-beam water image file in detail, and studying the nearest neighbor interpolation, improved nearest neighbor interpolation, two-dimensional linear interpolation and cubic polynomial interpolation, etc. The playback display of multi-beam water image and the abnormal extraction of water body are realized, and the control of playback speed is realized, which greatly improves the efficiency of data processing.
