The invention relates to a strip mine aerial survey method based on an unmanned aerial vehicle. The method comprises the following steps that image control points are arranged in a target area, and aerial survey image data of the target area are collected through an unmanned aerial vehicle aerial survey device; importing aerial survey image data into aerial survey software and stabbing an image control point; generating a point cloud model; collecting slope top and bottom lines and elevation points in the point cloud model; and the stripping amount is calculated through the collected slope top and bottom lines and elevation points. Through the unmanned aerial vehicle aerial survey device, strip mine data can be rapidly collected; in the surveying and mapping process, personnel do not need to enter the pit in the whole process, the safety risk under the pit is greatly reduced, meanwhile, large equipment in the open pit coal mine does not need to be stopped in the surveying and mapping process, and production loss caused by equipment acceptance pause is avoided.
本发明涉及一种基于无人机的露天矿航测方法,包括以下步骤:在目标区域布设像控点并通过无人机航测装置采集目标区域的航测影像数据;将航测影像数据导入航测软件并刺像控点;生成点云模型;采集点云模型中的坡顶底线和高程点;通过采集到的坡顶底线和高程点计算剥离量。本发明通过无人机航测装置能够快速对露天矿数据进行采集;在测绘过程中人员全程不需要进入坑下,大大减少坑下安全风险,同时在测绘过程中露天煤矿大型设备不需要停止,避免了因验收暂停设备所带来的生产损失。
