Abstract

The invention discloses an automatic model compounding analysis system and method for a building structure, and relates to the technical field of construction quality inspection. The invention aims at the problems that an existing structure model and design model alignment method is low in working efficiency, and quality detection precision cannot be controlled. The system comprises a digital scanning device, a target and a work station, the digital scanning device and the target are arranged in a to-be-detected space, the center point of the target and an actual reference datum point are located on the same vertical line, and the digital scanning device is in communication connection with the work station. The method comprises the steps: placing the target at the position of each actual reference datum point, enabling the center point of the target and the actual reference datum point to be located on the same vertical line, scanning a to-be-detected space, converting scanning data into a three-dimensional point cloud model, taking the coordinates of the center point of the target as the coordinates of the actual reference datum point, and converting the to-be-detected space design model into a lightweight skin grid model and setting a virtual reference datum point, so that the coordinates of the virtual reference datum point and the actual reference datum point coincide to complete model compounding.

Description

technical field [0001] The invention relates to the technical field of construction quality inspection, in particular to an automatic mold-closing analysis system and method for a building structure. Background technique [0002] In the construction process of construction projects, in order to ensure the key technical indicators of construction quality, the construction unit must construct according to the design drawings, and check the results after completing each process. With the increase of project scale and structure complexity, the requirements for structural construction quality inspection are getting higher and higher, and quality management personnel need to spend a lot of time comparing the construction site with the design drawings. [0003] At present, BIM technology is also gradually applied to construction quality inspection. The three-dimensional size data of the construction site is obtained through robotic total station, three-dimensional scanner or UAV ob...
