摘要
为满足潮间带大比例尺测图和三维建模等测绘需求,以某海岸带测量项目为基础,探索完成大面积(约6 km2)的泥沙滩无人机航测生产实践,在充分掌握潮汐变化规律基础上,制定周密规范的航摄和像控方案,实现高效、批量化生产潮间带标准化地理信息产品,定位精度满足1:500大比例尺测图需求。还提出了利用数字表面模型快速提取海岸线的新方法,实现了潮间带70%以上面积的测量作业,满足了《海道测量规范》中海岸地形测量需求,验证了无人机航测替代传统RTK碎部点测量实施潮间带地形测量的可行性。
In order to meet the needs of large scale topographic mapping and 3D modeling in the intertidal zone,based on a coastal zone survey project,this paper attempts to complete unmanned aerial vehicle measurement of a large area(about 6 square kilometers)of mud beach,and on the basis of the law of tidal changes,formulate a standardized aerial photography and image control point scheme,so as to achieve efficient and mass production of standardized geographic information in the intertidal zone,The positioning accuracy meets the needs of 1:500 large-scale mapping.This paper also proposes a new method to quickly extract the coastline by using the digital surface model,which realizes the measurement of more than 70%of the area of the intertidal zone,meets the requirements of Specifications for hydrographic survey,and verifies the feasibility of using unmanned aerial vehicle measurement to replace the traditional RTK detail survey.
