| description | The invention discloses a combined splicing method of multi-strip side-scan sonar images in a large area. The method includes the following steps of geometric transformation of the images; rotation and clipping; SURF (Speeded Up Robust Features) partition matching; feature splicing of geographic position error inducements and solution strategies; geographic standard redetermination after feature splicing of the multi-strip images; combined geocoding and feature splicing among the images. Compared with the prior art, the method has the advantages that the feature splicing efficiency of the multi-strip side-scan sonar images is improved, unification of image positions after feature splicing is achieved, and fine acquiring of a submarine geomorphic map in the large area is achieved.
本发明公开了种大区域多条带侧扫声呐图像的联合拼接方法，包括如下步骤：图像几何变换：旋转和裁剪；SURF(Speeded Up Robust Features)特征分块匹配；特征拼接的地理位置误差诱因及解决策略；多条带图像特征拼接后的地理基准重确定；图像间的联合地理编码和特征拼接。与现有技术相比，本发明提高了多条带侧扫声呐图像特征拼接效率，实现了特征拼接后图像位置统，实现了大区域海底地貌"张图"的精细获取。 |
