Method for site selection of inspection unmanned aerial vehicle landing point considering mountainous road terrain restrictions

Abstract

The application provides a mountainous area highway terrain restriction considering inspection unmanned aerial vehicle landing point site selection method, comprising: collecting terrain feature data and to-be-inspected facility position data of a target mountainous area highway region, and constructing a three-dimensional terrain constraint model; a multi-dimensional site selection evaluation index system for verifying candidate landing point regions is established; by using a spatial clustering technology, on the basis of the three-dimensional terrain constraint model, candidate landing point regions satisfying all constraint conditions in the multi-dimensional site selection evaluation index system are automatically screened; a comprehensive optimization model considering mountainous area site construction cost and inspection coverage is constructed, multi-objective optimization algorithm is used for evaluating and sorting the candidate landing point regions, and an optimal unmanned aerial vehicle landing point site selection scheme is output. The method improves the efficiency, safety and coverage integrity of mountainous area highway inspection, and provides key technical support for the large-scale application of unmanned aerial vehicles in the field of mountainous area traffic infrastructure operation and maintenance.
