Registered Point Clouds

Registered point clouds are one of the most fundamental and valuable outputs of 3D laser scanning. As an efficient and highly accurate method of collecting spatial data, 3D laser scanning captures existing conditions and geometry at a level of accuracy, speed, and detail that traditional survey techniques cannot match. A 3D laser scanner can collect up to millions of individual points per second, with each point containing its own X, Y, and Z coordinate. Combined with high-resolution HDR images captured by the 3D laser scanner, these points can be used to create colored point clouds. Together, these millions to billions of points form a point cloud—the least processed and most information-rich data format produced by 3D laser scanning.

Because registered point clouds preserve highly detailed as-built spatial data, they serve as the foundation for a wide range of downstream deliverables and applications. From registered point clouds, it is possible to create as-built 3D mesh models, 3D CAD models, BIM models, plant design models, and 2D CAD documentation. Registered point cloud data can also be used directly for inspection, storage tank inspection & calibration, volume surveys, construction verification, deformation & wear analysis, topographic mapping & georeferencing, propeller inspection, and VR/AR & 3D digital content. For clients who prefer to process or develop their own deliverables in-house, we can provide cleaned, colored, or black-and-white registered point clouds in a wide range of point cloud file formats, particularly for digital twin and engineering applications.

In larger terrestrial 3D laser scanning projects, registration quality becomes especially important. To achieve an even higher level of accuracy and reliability, we often establish survey control using total stations or laser tracker CMMs together with checkered and sphere targets. This is particularly valuable for large-scale or accuracy-critical work, where the higher angular and range accuracy of total stations and laser tracker CMMs can improve registration quality beyond what terrestrial 3D laser scanners alone can achieve. By incorporating survey control into the registration process, we can reduce measurement drift across large 3D laser scan datasets, strengthen overall quality control, georeference registered point cloud data to global coordinate systems or to a plant’s local coordinate system, and provide clients with a highly accurate digital representation of existing conditions that can be used immediately or developed further into application-specific deliverables.
