【摘要】：水下地形测量是进行海洋科学研究的基础,也是海洋测绘的重要工作内容。近年来,机载激光测深技术的提出与应用有效地弥补了以舰船为载体的传统声学测深方法在近海浅水区作业存在的技术缺陷,也为相关工程问题的解决提供了新的技术手段。详细介绍了机载激光测深技术的基本原理与误差来源,概括与总结了国内外研究机构在系统研制及其有关算法研究方面的进展情况,并在此基础上分析了该技术在近海浅水区域的作业优势与所存在的关键性问题,以供相关研究参考。最后,结合机载激光测深技术目前的研究现状对未来该技术可能的发展方向进行了展望。
[Abstract]:Underwater topographic survey is not only the basis of marine scientific research, but also an important part of marine mapping. The development and application of airborne laser sounding technology have effectively remedied the technical defects of the traditional acoustic sounding methods based on ships in offshore shallow water. It also provides a new technical means for solving related engineering problems. The basic principle and error source of airborne laser sounding technology are introduced in detail. This paper summarizes and summarizes the progress of research institutions at home and abroad in the field of system development and related algorithms, and on this basis, analyzes the operational advantages and key problems of the technology in offshore shallow water areas. Finally, combined with the current research situation of airborne laser sounding technology, the possible future development of the technology is prospected.
