船载激光扫描技术在海岸侵蚀监测中的应用

Application of Ship-borne Laser Scanning System in Coastal Erosion Monitoring

2009年以来,国家海洋局组织开展了沿海地区海平面变化影响调查和评估工作,海岸侵蚀监测是其重要组成部分。通过高精度船载激光扫描技术,可实现对海岸地形的高效、全覆盖、免接触三维数据采集。本文分析了船载激光扫描测量的技术特点,系统组成和关键技术,在此基础上,对深圳市重点岸段进行海岸侵蚀监测,并对测量结果进行分析。

Coastal erosion monitoring is an important part of sea-level work. High precision,full coverage and no contact 3D data acquisition is realized by high precision ship borne laser scanning technology. In this paper,the technical characteristics,system composition and key technology of the ship borne laser scanning measurement are analyzed. On this basis,the beach topographic survey of Xiasha village in Shenzhen is carried out and the results are analyzed.
