Engineering waste pile volume measuring method combining unmanned aerial vehicle and ground penetrating radar

Abstract

The invention provides an engineering waste pile volume measuring method combining an unmanned aerial vehicle and ground penetrating radar. By determining the propagation rate of the ground penetrating radar in a waste pile, the elevation of the lower surface of the waste pile can be accurately measured, the elevation of the upper surface of the waste pile is accurately acquired through unmanned aerial vehicle aerial photography and control point layout, the elevation difference between the upper and lower surfaces of the waste pile is calculated through a GIS, and then the waste pile volume can be worked out. By means of the method, the problem that the underlying surface of a waste pile cannot be distinguished due to long piling time of the waste pile can be avoided, and the problem thatthe waste pile volume cannot be accurately calculated by adopting satellite remote sensing images or independently using unmanned aerial vehicle aerial photography is also solved.

Description

technical field [0001] The invention relates to the technical field of engineering dump volume measurement, in particular to a method for measuring engineering dump volume combined with unmanned aerial vehicle and ground penetrating radar. Background technique [0002] With the rapid development of the economy, various production and construction projects are represented by point-type projects such as mining, hydropower stations, nuclear power stations, real estate, municipal infrastructure, and linear projects such as roads, railways, and pipelines. activities, seriously disturbed the surface, and produced a large amount of spoiled soil and dregs. Due to the steep slope of the piled waste, serious landslides, collapses, mudslides, high-sediment water flows and other disasters are likely to occur under heavy rain conditions if relevant protective measures are not taken. Especially those piled up around urban areas or above farmland are likely to pose a threat to life and pr...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the existing unmanned aerial vehicle cannot obtain the original underlying surface of the dumped body, resulting in the inability to accurately calculate the amount of dumped body, and proposes an engineering dumped body that combines unmanned aerial vehicles and ground penetrating radar Quantitative measurement method, UAV is used to measure the surface elevation of the dump, ground penetrating radar is used to measure the elevation of the lower surface of the dump, the measurement data of the upper surface and the lower surface are imported into ArcGis, and the volume of the dump can be accurately calculated through the 3D Analyst tool Poor, can solve the above problems very well
