摘要
针对海洋测绘中遇到的环境恶劣、任务繁重等情况,分析了机载Li DAR测深应用到海洋测绘中的可行性。介绍机载Li DAR测深原理、优势、典型设备,针对系统最大穿透深度、最浅探测深度、测点密度及测深精度等关键技术指标进行分析。最终得出结论,机载Li DAR测深符合海洋测绘的需求,应用到海洋测绘中是切实可行的。
Due to the poor environment and hard tasks encountered in marine surveying and charting, this paper analyzes the feasibility for the airborne LiDAR bathymetry application in marine surveying and charting. By introducing the principle, advantages and typical equipment of the airborne LiDAR bathymetry and analyzing the pivotal technique specifications of the maximum penetration depth, the shallowest exploration depth, density of survey points and depth accuracy, finally in conclusion that the airborne LiDAR bathymetry meets the requirements of marine surveying and charting,it is feasible to apply in marine surveying and charting.
