| 摘要: |
| 常规测量手段在潮间带滩涂区域测量作业中存在许多困难，采用了自主研发的无人机平台，搭载激光测距传感器、RTKGPS等设备进行空中三维地形数据采集，通过校验场人工测量结果比对，测量结果满足海域地形测量技术要求．本研究选择大潮期低潮时段，采用该平台获得了兴化湾附近多个海湾25ｋｍ２的滩涂地形数据和现场照片，按照规范要求进行处理成图，质量检验结果表明，测量成果满足规范要求，具有较好的实用性，在我国广阔的海岸带区域具有很好的应用空间． |

| Abstract: |
| It is difficult to measure the intertidal zone used conventional method in the topographic survey. In pres
ent study, we used laser range sensor and RTK GPS with a self-developed Unmanned Aerial Vehicle ( UAV) plat
form to obtain 3D topographical data. By comparing the results of UAV laser measurement with artificial field meas
urement, we found that UVA technique has met the technical requirements of sea topographic surveys. Using UAV
laser measurement technology, project team has got 3D topographical data and photographs according to the specifi
cation on several coves of 25 km2 areas near Xinghua Bay during the low tide period of spring tide. The quality inspection on 3D topographical data of several coves showed that the results of UAV laser measurement could meet the
specification requirements. Thus, the UAV laser measurement technology shall have a good practicability in the
wide coastal zones in China. |
