What is the difference between point cloud to BIM and scan to BIM (building information modeling) model?

“Scan-to-BIM” and “point cloud-to-BIM” are often used interchangeably to refer to the process of creating a 3D model of a building or structure from point cloud data. However, there can be a slight difference in the scope of the process depending on the context.

“Scan-to-BIM” often refers to the process of creating a BIM model from 3D laser scans of a building or structure. This typically involves using laser scanners to capture the geometry and dimensions of the building or structure and then using specialized software to convert the scan data into a BIM model.

“Point cloud-to-BIM” refers to the process of creating a BIM model from point cloud data, which can be generated using a variety of techniques, including laser scanning, photogrammetry, or lidar. This process involves importing the point cloud data into specialized software, and then using tools to extract relevant information, such as walls, floors, and other architectural features, to create a BIM model.

In general, both “scan-to-BIM” and “point cloud-to-BIM” involve similar processes and tools, and the end result is a BIM model that can be used for various purposes, such as design, construction, and maintenance. The main difference between the two is the source of the data used to create the BIM model, with “scan-to-BIM” relying primarily on laser scans, and “point cloud-to-BIM” being more flexible in terms of the source of the data used.
