摘　　要：内河天然航道滩险测量中,传统测量方法成果类型单一、精度效率低、人员安全无法保证。在无人机机载激光测深技术原理和方法的基础上,根据内河航道滩险测量特点,从探测能力、波浪改正、极浅水测量、飞行条件等多方面对其适用性进行论证,得出该技术灵活高效,可以提供高密度水陆地形点云数据,大大提高工作效率和成果精度,可以满足内河航道滩险测量需求,但需在提高极浅水测量精度、水质条件影响、回波识别处理技术、水面大比降影响等方面进行更深入的研究。In the measurement of inland waterway beach hazard, the traditional measurement method has the problems of single type of results, low accuracy and efficiency, and unguaranteed personnel safety.Based on the principles and methods of UAV airborne laser bathymetry technology, this paper demonstrates its applicability in terms of detection capability, wave correction, very shallow water measurement, flight conditions and other aspects based on the characteristics of inland waterway beach hazard measurement. It concludes that the technology is flexible and efficient, it can provide high-density terrain point cloud data on water and land, which greatly improves the efficiency and accuracy of results, and it can meet the needs of inland waterway beach hazard measurement, but more deeper research is needed to improve the accuracy of very shallow water measurement, the impact of water quality conditions, echo identification processing technology, and the impact of large specific drop on the water surface.
