The present invention relates to a method and device for automatically generating a 3D model for each component of a bridge using a drone. The method for automatically generating a 3D model for each component of a bridge using a drone performed by the device for automatically generating a 3D model for each component according to the present invention comprises: a first step of collecting photo data of various angles of a bridge using a camera mounted on a drone; a second step of assigning semantic information on the components of the bridge by applying semantic segmentation based on artificial intelligence to the collected photo data; and a third step of generating a 3D model of the bridge to which the semantic information is assigned by applying SfM (Structure from Motion) to the photo data to which the semantic information of the components of the bridge is assigned. Accordingly, the present invention is intended to enable the automatic production of a building information model (BIM) of a bridge.
