大比例尺无人机航片成图精度研究
|
摘要
无人机的兴起及应用,极大地改变了许多测绘项目的作业方式。然而,由于无人机本身的特点,其无法挂载专业的航摄设备,从而使得传统的航摄规范不适用于无人机测绘,而目前的规范其精度要求太低,已经无法适应工程项目的实际需求。本文以此为研究目标,着重研究了像控点的布设数量与成图精度方面的关系。
The emergence and application of UAV greatly changed the way of operation of many surveying and mapping projects. However,because of the characteristics of the UAV,it is unable to mount professional aerial photography equipment,which makes the traditional aerial photography specifications do not apply to the UAV surveying and mapping,and the current standard is too low in precision and cannot meet the actual needs of the project. Taking this as the research objective,this paper focuses on the relationship between the layout of image control points and the accuracy of mapping.
