摘要
露天矿山地形起伏大、构造复杂,为解决露天矿山传统测绘难度大、不安全的难题,提出了利用无人机倾斜摄影和三维激光扫描技术进行三维模型重构以得到倾斜实景三维模型、三维激光点云模型等多源数据的方法,并对模型精度进行了实地验证。经实际应用,此种方法解决了无人机竖直航摄、无人机倾斜摄影的一些问题,在露天矿山土方量算、生态评估、地图制作、工程规划等方面具有较好的应用价值。
Open-pit mines have a large terrain fluctuation and complex structure.In order to solve the difficulty and insecurity of traditional surveying and mapping of open-pit mines,a method of 3D model reconstruction using UAV Oblique Photography and 3D Laser Scanning technology is proposed,and obtains multi-source data such as tilted realistic 3D model and 3D laser point cloud model,and verifies the accuracy of the model on the spot.Through practical application,this method solves some problems of UAV Vertical Aerial Photography and UAV Oblique Photography,and has good application value in earthwork calculation,ecological assessment,map making,engineering planning and other aspects of open-pit mines.
