3Dprofil

3Dprofil is a term used in the field of 3D metrology and digital geometry to describe the representation and analysis of three-dimensional surface profiles. It refers to processes that capture, store, visualize, and quantify the shape of a surface along a defined path or contour on an object.

Data models for 3Dprofil profiles can be represented as parametric curves, polylines, or dense point clouds with coordinates, direction vectors, and measurement uncertainty. The choice of model depends on the application and the required resolution of the profile.

Acquisition methods span both contact and non-contact techniques. Stylus profilometry provides high-resolution cross-sections, while laser scanning, structured light, and photogrammetry capture profiles over larger areas. Multi-sensor configurations enable profiling at multiple scales or viewpoints.

Processing and analysis workflows include data alignment and registration, noise reduction, and smoothing. Features such as peak heights, valley depths, and surface roughness can be extracted, and profiles can be compared against reference definitions to support tolerance verification and wear analysis.

Applications of 3Dprofil concepts include quality control in manufacturing, reverse engineering, surface integrity assessment, and monitoring wear or deformation in mechanical components. It also finds use in architectural conservation and paleontological or archaeological surface studies.

Interoperability and standards: there is no single formal standard named 3Dprofil. The term is used variably by vendors and researchers to describe pipelines that may exchange data in standard formats such as STL, OBJ, or PLY, with metadata in XML or JSON. See also profilometry and 3D scanning.
