Abstract

The invention relates to an application method of a three-dimensional scanning technology in building engineering based on a BIM. The method comprises the steps of scanning a construction site and surroundings through the three-dimensional scanning technology, and generating data; establishing a BIM three-dimensional model of the construction site and the surroundings; guiding site construction through the BIM three-dimensional model of the construction site and the surroundings; establishing a BIM three-dimensional model of design paper; establishing a BIM three-dimensional model of a finished process; comparing the BIM three-dimensional model of the design paper with the CAD model of the paper of a designing institute or the BIM three-dimensional model of the design paper; and modifying or perfecting the finished process if there are deficiencies or defects.

Description

technical field [0001] The invention relates to an application method of a BIM-based three-dimensional scanning technology in construction engineering, and belongs to the technical field of construction engineering. Background technique [0002] Three-dimensional scanning is a high-tech that integrates optical, mechanical, electrical and computer technologies. It is mainly used to scan the spatial shape, structure and color of objects to obtain the spatial coordinates of the object's surface. Its significance lies in the ability to convert the three-dimensional information of the object into a digital signal that can be directly processed by the computer, which provides a very convenient and quick means for the digitization of the object. In the current construction field, under the background of the big data era of the Internet of Things, the Building Information Model (BIM) has emerged as the times require, and has been rapidly promoted and developed. The combination of t...
