The present invention relates to a method for acquiring and processing various three-dimensional data to produce a precise wide-area scale model. The method for acquiring and processing various three-dimensional data to produce a precise wide-area scale model comprises: a type selection step (S10) of acquiring and post-processing, in various manners, three-dimensional data required to produce a wide-area scale model and classifying a type according to a type and a structure of a building to produce a more precise model; a scale selection step (S20) of selecting a size of the model to be produced; and a processing step (S30) of collecting and processing the three-dimensional data. The processing step (S30) includes at least one of the steps of extracting and drawing a CAD drawing by extracting an edge of three-dimensional scanning data (S30-1); extracting and drawing a vector line by photographing an actual image (S30-2); extracting and drawing the vector line through Google map and map service images (S30-3); and acquiring and processing data to produce a geographical base (S30-4). |
