【摘要】：多波束水體影像近年來(lái)得到了廣泛的應(yīng)用,但由于缺少格式標(biāo)準(zhǔn),各多波束廠商所支持的格式各不相同,給進(jìn)一步的數(shù)據(jù)處理帶來(lái)了一定的困難�；贛atlab平臺(tái),通過(guò)對(duì)ALL格式多波束測(cè)深數(shù)據(jù)文件與WCD格式多波束水體影像文件進(jìn)行了詳細(xì)的解析,并且研究了最近鄰插值、改進(jìn)最近鄰插值、二維線性插值與三次多項(xiàng)式插值等多種算法,實(shí)現(xiàn)了多波束水體影像的回放顯示與水體異常提取,并且實(shí)現(xiàn)了回放速度的控制,極大地提高了資料處理效率。
[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.
