| 摘 要： | 以多波束精确的水深数据为参照源,采用原始回波时间对多波束测深数据与其同源声纳数据进行匹配,从而获得高精度和高分辨率的海底影像数据,并避免了传统声纳图像处理过程中斜距改正所带来的几何形变。匹配结果采用光照图输出,并与三维水深图、原始声纳图像和CARIS处理后的声纳图像进行比较分析。该方法有效地提高了多波束数据的利用率,增强了对海底地形的探测分辨率。

| Abstract: | Fusion of multibeam sonar data and bathymetry data have great signification in seafloor detection.According to high precision bathymetry data,high resolution seafloor backscatter data will be get by the fusion of multibeam sonar data and bathymetry data.The method uses raw echo time to make the fusion which avoids distortion in sonar data procession by traditional ways.The fused data is showed by shaded relief map and compared with 3D bathymetric map,raw grayscale map and grayscale map processed by CARIS.Th... |
