Abstract

The invention relates to the technical field of road disease detection, in particular to a pavement subsidence detection method and device based on satellite and unmanned aerial vehicle remote sensing. The method comprises the following steps of: acquiring original SAR image data of a to-be-detected road section; extracting sedimentation rate information; determining a potential occurrence position of pavement subsidence; making an inspection scheme of an unmanned aerial vehicle carrying a laser radar for reinspection; conducting road surface point cloud data processing; and judging the subsidence condition of a pavement. According to the pavement subsidence detection device and method based on satellite and unmanned aerial vehicle remote sensing, the potential position where pavement subsidence possibly occurs is found out according to the subsidence rate distribution condition, preliminary detection of pavement subsidence is achieved within a large range, the advantages of the InSAR technology are fully utilized, and manual field operation is reduced; and rapid detection of pavement subsidence is realized, the detection method is innovative, and the detection efficiency is relatively high.

Description

technical field [0001] The invention relates to the technical field of road disease detection, in particular to a road surface subsidence detection method and device based on satellite and UAV remote sensing. Background technique [0002] Pavement subsidence refers to the phenomenon that the road surface sinks due to the vertical deformation of the roadbed. When the driving vehicle passes through subsidence, a large impact load is generated, and the vehicle appears "bumping", which seriously affects the safety and comfort of the road, and reduces the performance and service level of the road. If the subsidence of the road surface is not maintained in time, the subsidence area will develop rapidly, and the downward development will cause damage to the grassroots and even the roadbed. "Highway Technical Condition Evaluation Standard" JTG5210-2018 defines road subsidence as local subsidence of the road surface greater than 10mm, providing a basis for its rapid detection. The ...
