A method for measuring the volume of engineering dumps combined with unmanned aerial vehicle and high-density resistivity method

Abstract

The invention provides an engineering spoil bank amount measurement method with combination of a UAV (unmanned aerial vehicle) and a high-density resistivity method. According to the method, apparentresistivity in a project area (containing spoil bank)is measured with the high-density resistivity method, the spoil bankcondition in the project area and the marginal soil condition are surveyed in combination with the early stage, a result of the high-density resistivity method is interpreted, then underlying surface elevation information of the spoil bank can be accurately analyzed, surface elevation of the spoil bank can be accurately acquired through UAV aerial photography and control point location layout, upper and lower elevation difference of the spoil bank is calculated by the GIS (geographic information system), and therefore, the spoil bank amount can be calculated; the problem that the underlying surface cannot be distinguished due to longer dumping time of the spoil bank canbe solved, and the problem that the spoil bank amount cannot be accurately calculated according to satellite remote sensing images by independentUAV aerial photography is also solved.

Description

technical field [0001] The invention relates to the technical field of engineering waste volume measurement, in particular to a method for measuring engineering waste volume combined with an unmanned aerial vehicle and a high-density resistivity method. 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 ...

AI Technical Summary

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 a project combining unmanned aerial vehicle and high-density resistivity method The method of measuring the amount of dumped waste, using drones to measure the surface elevation of the dumped body, and the high-density resistivity method to measure the height of the bottom of the dumped body, import the surface and bottom elevation data into ArcGis, and use the 3D Analyst tool to accurately calculate the dump The volume of the body can solve the above problems well
