Robotic Imaging: What is Level of Detail (LOD)?

In laser scanning, Level of Detail (LOD) is the term used to describe the resolution of the 3D scan. The higher the LOD, the more detail is captured in the scan. This is important because it determines how accurately the object can be reproduced. If you need a high level of accuracy, you'll need to use a scanner with a high LOD.

When it comes to hiring someone to do a laser scan-to-BIM project, you have a few different level of detail options to choose from. The first is the point cloud, which is the most basic level of detail and captures the outline of the object scanned. The second is the mesh, which adds surface detail to the point cloud. And finally, there is the solid model, which creates a 3D model with all of the surface detail included.

The level of detail you choose will depend on your needs and what you're trying to achieve with your project. If you just need an outline of the object scanned, then the point cloud is a good option. If you need more surface detail, then the mesh is a better choice. And if you need a 3D model with all of the surface detail included, then the solid model is your best option.

The terms "level of development" and "level of detail" can be used interchangeably, but they have different meanings. "Level of development" refers to the stage of development a project is in. The six different levels of development, defined by the American Institute of Architects, are conceptual, schematic, design development, construction documents, bidding and construction, and occupancy. "Level of detail" refers to the resolution of the 3D scan. The higher the LOD, the more detail is captured in the scan.

An "as-built" model is a 3D model that captures the actual condition of a building or structure after it has been constructed. It's used to document the physical state of the building and can be used for maintenance and repair purposes.
