Rapid engineering quantity statistical method based on three-dimensional laser scanning and live-action three-dimensional modeling

The invention provides a rapid engineering quantity statistical method based on three-dimensional laser scanning and live-action three-dimensional modeling, and the method comprises the following steps: S1, employing an unmanned plane to scan the outdoor appearance of a building, and generating an outdoor model; when the unmanned aerial vehicle is adopted to scan the outdoor appearance of the building, the method further comprises the following steps that S11, a three-dimensional space coordinate axis is established, and a current engineering coordinate datum point is determined; s12, inputting a coordinate reference point to a three-dimensional laser scanner and an unmanned aerial vehicle remote control end; s13, obtaining the coordinates of the current scanning component; an unmanned aerial vehicle is adopted to scan the outdoor appearance of a building, and an outdoor model is generated; according to the method, indoor components of a building are scanned in cooperation with a three-dimensional laser scann
