What Level of Detail can you expect from a 3D laser survey?
When capturing scan data, you are essentially creating a precise snapshot of a specific moment in time. However, once you possess this data, it’s crucial to determine how much of it is actually relevant, as an excessive amount can be as inconvenient as an insufficient amount.
It’s important to note that the original scan data can always be referred back to, so when it comes to modelling, it’s sometimes better to leave out information that may not necessarily be required. In some cases, less is more.
To ensure client satisfaction, PointSCAN utilises a level of detail scale that clearly outlines the anticipated outcome. After all, there’s nothing more disappointing than expecting a Ferrari and receiving a Morris Minor, and the same applies to our documentation.
Although our levels of detail can be used in conjunction with one another, it is advisable to prioritise which items necessitate a higher level of detail. For instance, you may require detailed information regarding certain objects in a room but only need to acknowledge the room’s existence, without going into extensive detail. By doing so, you will be able to effectively manage file data sizes and avoid processing issues when importing into third-party applications.
PointSCAN's Four Levels of Detail
PointSCAN delivers a basic level of detail for the final output. This will include a basic 3D model of the scanned object, building or area, with a limited amount of detail. The model may include basic shapes, contours, and dimensions of the scanned object, but may not capture all of the finer details. This level of detail is suitable for basic visualisation and measurements.
PointSCAN provides a higher level of detail for the final output, producing a 3D model of the scanned object, building or area with more intricate shapes, finer contours, and more precise dimensions than the basic level. Such a model proves suitable for advanced visualisations and precise measurements, meeting the requirements of more demanding applications.
PointSCAN provides a comprehensive and accurate 3D model of the scanned object, building or area. The model includes fine details such as textures, patterns, and surface finishes, resulting in a highly realistic and visually captivating final output. This level of detail is ideal for use in high-end visualisation, quality control, and production applications where precision and accuracy are paramount.
PointSCAN generates an ultra-high level of detail in its final output. The 3D model generated at this level is the most precise and accurate, incorporating intricate features such as microstructures, surface defects, and complex geometries. This level of detail is particularly useful for advanced research, analysis, and design purposes where accuracy and precision are crucial. The output is of the highest quality, making it suitable for advanced research, analysis, and design purposes.
How much does each Level of Detail cost?
Everything comes at a cost, and it’s up to the client to decide whether it’s worth the investment for their project. PointSCAN breaks down their costs into three categories: Acquisition, Documentation, and Digital Transformation.
Acquisition – refers to capturing 3D data using a 3D scanning device, such as a laser scanner. The scanning device captures millions of points in space, which form a point cloud – a collection of 3D points that represent the surface of an object, building or environment. The acquisition process typically involves setting up the scanning equipment, positioning it correctly, and then running the scanning process. Once the scanning process is complete, the point cloud data is generated.
Documentation – includes organising, annotating, and storing the point cloud data. This involves processing the data to remove any noise or errors, and then exporting the data into file formats such as OBJ, E57, or LAS. These files can then be stored and shared with others who need to access the point cloud data. Documentation is an important step in the 3D scanning process, as it ensures that the data is properly organised and can be used effectively in downstream processes.
Digital Transformation – refers to the process of using software tools to enhance and animate the point cloud data. This can involve using 3D modelling software to create 3D models. The digital transformation process adds value to the data by making it more useful and accessible for a variety of applications, such as architecture, engineering and construction.
While there is a physical cost associated with attending a site, it’s important to note that traditional surveys would also have incurred a cost. The price of a day (up to 8 hours) of scanning can vary between suppliers and applications, but typically ranges from £550 to £1000.
The cost of Documentation, on the other hand, depends on multiple factors, including the quantity and level of detail required in the final output files, as well as the amount of time it takes to produce them. As a result, the cost of documentation typically increases by at least 70% for each subsequent level of detail, with LOD1 costing £100, LOD2 costing £170, LOD3 costing £279, and LOD4 costing £491. Similarly, Digital Transformation costs are also influenced by timing and staff costs.
