The invention provides a building earthquake damage scene construction method and
system based on an unmanned aerial vehicle
remote sensing image, and relates to the technical field of urban
earthquake resistance and disaster prevention, and the method comprises the steps: constructing a three-dimensional
space model of a building through an urban earthquake damage
simulation system, and determining the
nonlinear model parameters of the building; carrying out earthquake damage scene construction by taking a single building as
granularity by adopting an elastic-plastic time-history
analysis method, and determining a building damage index; according to a mapping relation between a preset building damage index and a building earthquake damage
risk level, determining an earthquake damage
risk level of each building; and according to the building
list, the anti-seismic performance of the building with the specified earthquake damage
risk level is detected, and anti-seismic measures corresponding to the building with the specified earthquake damage risk level are generated. According to the geometric attribute information of the building, the three-dimensional
space model is constructed in combination with the urban earthquake damage
simulation system, the earthquake damage risk level of the single building is accurately divided, and the refinement level of urban
earthquake resistance and disaster prevention is improved in combination with
earthquake resistance measures.
