无人机航测技术在海产养殖证据保全中的应用

Application of UAV Aerial Photogrammetry in Evidence Preservation of Mariculture

海产养殖证据保全无人机航测不同于陆地航测,航测目标均在海面上,受潮汐影响,海上目标时刻移动,这给海上航测带来巨大困难。本文结合实际工程项目,通过大量试验及分析,通过从无人机选择、航线设计、像控测量、航飞时机、内业空三平差等各个流程进行优化设计,最终DOM成果达到1∶2000精度,满足海产养殖证据保全要求。

The UAV aerial photogrammetry for evidence preservation of mariculture is different from the land aerial photogrammetry,the aerial survey targets are all on the sea surface,affected by the tide and moved at any time,which brings great difficulties.This article combined with the actual project,through a large number of tests and analysis,through the UAV selection,route design,image control measurement,flight opportunity,aerotriangulation and other processes to optimize the design,the final DOM results achieve 1∶2000 precision,to meet the requirements of mariculture evidence preservation.
