摘　　要：无人机航测在各个领域的使用逐渐广泛化,然而还是存在一定的条件下拍摄的精度很难满足行业要求。成图精度除了受制于工具使用以外,还与工作姿态和位置等因素有关。基于此,本文提出影响低空无人机航测露天矿地质成图精度的因素研究,从无人机航测高度、相机、像片倾角、像控点、飞行姿态、相机放置方式、无人机平台七个方面进行阐述。UAV aerial survey is widely used in various fields,but there are still some conditions,the accuracy of photographing is difficult to meet the industry requirements.The accuracy of mapping is not only restricted by the use of tools,but also related to working attitude and position.Based on this,this paper puts forward the research on the factors affecting the accuracy of geological mapping of low altitude UAV aerial survey of open-pit mine,including UAV aerial survey altitude,camera,photo tilt angle,image control point,flight attitude,camera placement mode and UAV platform.
