无人机数码航空影像大比例尺地形图测绘可行性研究
|
摘要
无人机具有机动灵活、成本低廉及生产周期短等优点,但通过无人机数码航摄方式获取的影像数据,存在姿态角偏大及镜头畸变等问题,对于其是否适用于大比例尺地形图测绘,一直受到业内的强烈关注。为此,文章首先分析了无人机数码航摄数据采集方式的优劣性,然后阐述了利用无人机影像测绘地形图的作业流程,包括数码航摄、影像预处理、空三加密、DLG采集、调绘编辑成图5个步骤;最后利用相关数据进行试验,验证了基于无人机数码航摄影像测绘大比例尺地形图的可行性。
Unmanned aerial vehicle( UAV) has the advantages of flexible,lower production consumption and shorter production cycle,but the disadvantages of Unmanned aerial vehicle are also obvious,such as,the transfinite posture angle and the lens distortion of the digital aerial images,for it is suitability for large scale topographic map production has been strong focused on in the surveying and mapping industry.Therefore,this paper first analyzes the advantages and disadvantages of the Unmanned aerial vehicle,and then expounds the process of surveying and mapping topographic maps using Unmanned aerial vehicle image,Including digital aerial photography,image preprocessing,aerial triangulation,digital line graph acquisition,editing and mapping into five steps,finally using the relevant data to test and verify the feasibility of the Unmanned aerial vehicle image based large scale topographic map production.
