Abstract: | The positioning of building structural components is the key to automatic progress tracking. In the existing
research results, the monitoring object is a simple construction site, and the form of today’s buildings is increasingly
complex and is mainly of cast-in-place concrete structure. In order to track the construction progress of this kind of
building, based on building information modeling (BIM) and computer vision (CV) technology, a method was
proposed to locate the structural members of cast-in-place concrete building from the top view. Firstly, target detection
technology was employed to identify the structural components in the construction state from the top view of the
construction site. The BIM elements were projected onto the imaging plane based on the principle of camera imaging.
Finally, the mapping relationship between the actual components and BIM elements was established through the
results of registration and projection, so as to realize the automatic positioning of structural components. The
experimental results show that the recognition accuracy is 82.08% and the registration rate is 94.17%. The recognition
and registration effect of the plane formwork is the best. Compared with the similar methods, this method reduces the
degree of occlusion, makes full use of the context information, and is more in line with the actual construction process.
It provides a new scheme for the construction process tracking of complex buildings. |
