摘要
在海道测量领域,有关多波束声纳水柱影像的应用研究已成为当前的前沿和热点问题之一。分析了影响水柱影像质量的主要因素,阐述了水柱数据采集的参数设置和影像判读的一些要点。通过在南海区的几个实践案例的分析,对水柱影像在水下障碍物探测中扫测细小物体、获取目标详细特征等作用进行了验证,说明了水柱影像在多波束声纳底部检测的质量控制方面存在的优势,最后提出了目前面临的一些问题和应用前景。
In Hydrographic Surveying,the application of multi-beam sonar water column image (WCI) has become one of the frontiers and hot issues currently.This paper analyzes the main factors affecting the quality of WCI,and expounds parameters'setting of data acquisition and the matters needing attention in image interpretation.Based on the analysis of several practical cases in the South China Sea,the results show that WCI can be used to detect small objects and obtain detailed features of the target in underwater obstacle detection,and illustrate the advantages of WCI in quality control of multi-beam sonar bottom detection.Finally,some existing problems and application prospects are presented.
