Cloud2BIM automates the Scan-to-BIM process by converting point clouds into 3D parametric entities. It employs a segmentation algorithm that utilizes point cloud density analysis, augmented by image and morphological operations. This allows the software to precisely extract the geometry of building elements such as slabs, walls, windows, and doors. The output is generated in IFC format, ensuring compatibility with other OpenBIM tools. The primary motivation for this software is to streamline and enhance decision-making at the end of a building's lifecycle, leading to more efficient material use during demolition or deconstruction.

To install Cloud2BIM, follow these steps: git clone

https://github.com/VaclavNezerka/Cloud2BIM.git

Install dependencies:

First, ensure you have Python and pip installed. Then, install the required dependencies listed in the requirements.txt file:

pip install -r requirements.txt

The cloud2entities.py script requires a YAML configuration file to run. You can provide the path to the configuration file as a command-line argument. If no argument is provided, the script will automatically use the default file config.yaml.

python cloud2entities.py config.yaml

The complete original point cloud for Kladno station is available at Zenodo platform.
