倾斜摄影测量技术在露天矿监测中的应用

Application of Oblique Photogrammetry in Opencast Mine Monitoring

针对露天矿区范围较大、地形情况复杂等特征,提出了利用倾斜摄影测量技术进行露天监测工作的方法。根据设定的航线对测区进行影像拍摄,再对影像进行内业处理,从而建立测区的实景三维模型。该方法是一种无接触式量测技术,自动化程度较高,摄影范围较大,较好地弥补了传统测量方式在露天矿监测中的不足之处,大大提高了露天矿的监测效率。实验结果表明,该技术不仅可减少工程项目的工作量,而且其高精度的实景三维模型具有多种应用作用。

The opencast mine area is large and the terrain is complex.On the basis of this,we put forward an opencast monitoring method based on oblique photogrammetry.According to the set route,we collected the images of survey area,and then processed the images internally.Finally,we established the 3D real scene model of survey area.This method is a non-contact measurement technology,which has high degree of automation and large range of photography,makes up for the shortcomings of traditional measurement methods in the opencast mine monitoring,and greatly improves the monitoring efficiency.The experimental result shows that this method can not only reduce the workload of engineering projects,but also have a variety of applications of high-precision 3D model.
