| 中文摘要: |
| 随着水下环境和水声信道随时间动态变化，合成孔径声纳形成的地貌或目标结果均会随之变化，导致目标漏检和场景认知度低的问题，对水下安防和无人导航等带来较大隐患。针对该问题，本文提出了基于双时相的合成孔径声纳变化目标检测方法，根据帧间声图地理信息和特征的匹配，完成像素级的差异分析比对，实现变化目标的检测和标注。经试验数据验证，该方法能够准确检测和标注预设的变化区域，为水下场景变化规律的掌握和威胁目标的监测具有重要意义。 |
| 英文摘要: |
| With the change of underwater environment and channel over time, the target results and geomorphology produced by synthetic aperture sonar will alter as well. This lead to the problems of target missing detection and low scene awareness, which brings danger to underwater security and unmanned navigation. This research suggests a dual-time-phase changing target detection method to address this problem. Firstly, the inter-frame acoustic map matching based on geographic information and feature is carried out, followed by pixel-level difference analysis and comparison, and finally the detection and labeling of change targets is realized. Verified by the test data, the method can accurately detect and label the preset change area, which is of great significance for the mastery of the change rule of underwater scene and the monitoring of threat targets. |
