Laser Bathymetry(激光测深)研究综述
Laser Bathymetry 激光测深 - Laser bathymetry, improvement and development of optical methods and instrumentation for marine environment studies. [1] SH) uses the method of laser bathymetry, which replaces ship-based hydrographic surveys in shallow water areas of the Wadden Sea and the coastal areas of the North Sea and Baltic Sea. [2] The physical fundamentals of laser bathymetry based on measuring the halo radius resulting from diffuse scattering of a laser beam at the bottom of a water body and re-incidence of scattered light on the bottom after reflection from the underside of the water surface have been developed. [3]激光测深、改进和开发用于海洋环境研究的光学方法和仪器。 [1] SH) 使用激光测深方法，在瓦登海浅水区以及北海和波罗的海沿岸地区取代了船基水文测量。 [2] 激光测深的物理原理基于测量激光束在水体底部的漫散射和从水面下侧反射后散射光在底部重新入射所产生的光晕半径。 [3]
Airborne Laser Bathymetry 机载激光测深
Ocean waves are a vital environmental factor that affects the accuracy of airborne laser bathymetry (ALB) systems. [1] Besides airborne laser bathymetry and multimedia photogrammetry, spectrally derived bathymetry provides a third optical method for deriving water depths. [2] The full-area surface measurement of the river bed was made by means of airborne laser bathymetry and echo sounding. [3] The paper describes the acquisition of the submerged topography of the federal waterway and river Elbe during the low discharge period in 2018 using airborne laser bathymetry, also referred to as airborne hydromapping. [4] This special issue constitutes a collection of scientific papers and reports mainly focussing on optical methods for bathymetry derivation including airborne laser bathymetry, multimedia photogrammetry, and spectrally derived depth estimation. [5] Airborne Laser Bathymetry (ALB) is an attractive technology for the measurement of shallow water bodies because of the high acquisition rate and high point densities that can be achieved. [6] Modern full-waveform laser bathymetric scanners offer the possibility of a practical application of airborne laser bathymetry (ALB) data algorithms as a valuable source of information in the study of the aquatic environment. [7] On the basis of the studies conducted, it was concluded that the use of a secondary analysis of a full waveform of the airborne laser bathymetry allowed for the identification of objects on the seabed. [8]海浪是影响机载激光测深 (ALB) 系统准确性的重要环境因素。 [1] 除了机载激光测深和多媒体摄影测量之外，光谱衍生测深提供了第三种光学方法来推导水深。 [2] 采用机载激光测深和回声测深的方法对河床进行了全区域表面测量。 [3] 该论文描述了在 2018 年低流量期间使用机载激光测深仪（也称为机载水文测绘）获取联邦水道和易北河的水下地形。 [4] 本期特刊是一系列科学论文和报告，主要关注用于测深推导的光学方法，包括机载激光测深、多媒体摄影测量和光谱推导深度估计。 [5] 机载激光测深 (ALB) 是一种有吸引力的浅水体测量技术，因为它可以实现高采集率和高点密度。 [6] 现代全波形激光测深扫描仪为机载激光测深 (ALB) 数据算法的实际应用提供了可能性，作为研究水生环境的宝贵信息来源。 [7] 根据所进行的研究，得出的结论是，对机载激光测深仪的完整波形进行二次分析可以识别海床上的物体。 [8]
