Research on Registration Method Based on Point Cloud Data and BIM Model
With the rapid development of the construction industry,3D point cloud scanning technology and automatic registration of BIM model have become a hot research topic.Nowadays,the technological de-velopment of construction engineering has become an inevitable trend,and only by relying on modern sci-ence and technology can a higher level of construction work be achieved.Based on this,with the rapid de-velopment of BIM technology and the 3D display of 3D laser scanning technology,the 3D coordinate data of the target can be obtained at a non-contact speed and accurately,and the 3D digital model of the target building can be established through the processing of software in the industry.Point cloud data has the ad-vantages of high accuracy of geometric information and true restoration of construction site,while BIM has rich geometric construction information.This paper proposed a rough registration method of 3D point cloud using BIM grid model,focusing on the plane as geometric feature,which is used to align 3D point cloud with BIM grid,so as to realize the monitoring of building construction progress,and provide the possibility for the construction industry to achieve intelligence and precision.
