The invention discloses a method for rapidly constructing a three-dimensional
terrain model by use of an unmanned aerial vehicle for multi-
view camera shooting, the method comprises the following steps: collecting
terrain information of a region to be surveyed; selecting a type of the unmanned aerial vehicle for aerial camera shooting according to the
terrain information of the region; using
control software to upload a flight mission to the unmanned aerial vehicle to enable the unmanned aerial vehicle to fly according to a predetermined
flight altitude and flight path and meanwhile
shoot the ground from multiple perspectives; using 3D model generation
software to process collected images to reconstruct the three-dimensional model of the shot region. By use of the flying stability and flexibility of the multi-rotor unmanned aerial vehicle, low-altitude
remote sensing measurement can be performed based on the theory of three-dimensional reconstruction of the images,
automation and intelligence of a
geographic mapping process can be realized through flight path planning and multi-
view camera shooting of the unmanned aerial vehicle, precision and efficiency of geo-mapping can be improved, the
workload in the geo-mapping is greatly reduced, and the method has the advantages of high degree of
automation, large measuring range, low cost and convenient operation and the like.
