| 摘 要： | 水深测量是海洋测绘的重要内容。传统的船载多波束回声测深方法虽然具有较高的测量精度，但无法进入沿岸浅水区域和海礁密集区域。近年来，机载LiDAR的出现和发展填补了沿海浅水区域水深测量技术的空白，已成为一种快速高效的水深及海底地形探测方法。本文介绍了现有的几种有代表性的机载激光测深系统，给出了机载激光测深数据处理流程，分析了机载激光测深的关键技术，归纳并总结了该技术目前所存在的技术难点和未来的发展趋势。

| Abstract: | Bathymetry is the basic work of marine surveying and mapping. Traditional shipboard sonar systems, such as muhi-beam echo sounders, have high accuracy when used in ocean depth measurement. But they tend to have access prob- lems in the coastal zone where the water is shallow with poten- tial reefs. In recent years, the newly-born Airborne Laser Ba- thymetry （ALB）technology plays as a good supplementary meth- od in data aquisition of coastal water depth. It turns to be a rap- id and effective way to detect the water depth and the topogra- phy of the seabed. This paper introduces several famous ALB systems, shows the bathymetric data processing workflow, analyzes the key technologies, and summarizes ALB＇ s existing problems and developing trends. |
