船载水陆一体化综合测量系统研究进展

The development of shipborne over water and under water intergrated mapping system

海岛、海岸带等水陆结合部一直是开展海洋测绘的困难区域。近年出现的机载激光测深技术尽管可应用于海岸带、海岛礁等区域的测量,但由于受限因素较多,未能实现我国大部分水陆地形的无缝拼接工作。船载水陆一体化综合测量技术通过多进程网络技术集成三维激光测距、多波束测深、定位定姿等技术,弥补了传统测量方式低效率、高成本、获取水陆高密度的三维空间地理信息困难等不足,作为新兴的海洋空间探测技术优势明显。本文概述了目前国内外船载水陆一体化综合测量系统的最新研究进展,并对系统组成及原理进行了介绍,同时总结了系统的数据采集、处理流程中的关键环节及存在的问题,最后展望了其未来的发展趋势。

Islands,coastal zones and other areas have been difficult areas for marine surveying and mapping.In recent years,airborne laser bathymetry can be applied to coastal zones,islands and reefs survey,but due to many constraints,it is unable to achieve seamless mosaic of water and land topography in China.Shipborne over water and under water intergrated mapping technology integrates threedimensional laser ranging technology,multibeam sounding technology,position and orientation technology through multi-process network technology,which makes up for the shortcomings of traditional surveying methods,such as low efficiency,high cost,difficulty in obtaining high-density water and land three-dimensional spatial geographic information.As a new marine space exploration technology,it has great advantages.This paper summarizes the latest research progress of the shipborne over water and under water intergrated mapping system at home and abroad,expounds its system composition and principle,summarizes the key links in the data acquisition and processing flow of the system and the existing problems of the system.At the same time,it looks forward to its future development trend.
