Core Concepts2 entries

What Is 3D Scanning? Principles, Workflow, and Industrial Applications 3D scanning is a digital measurement technology that converts the surface geometry of physical objects into 3D data. This entry covers its working principles, core parameters, industrial use cases, common misconceptions, and related technical concepts. What Is a 3D Scanner? Types, Parameters, and Selection Criteria A 3D scanner captures three-dimensional surface data from physical objects and converts geometry, dimensions, and features into digital data for inspection, reverse engineering, and modeling.

Data And Accuracy2 entries

What Is 3D Scanning Accuracy? Accuracy, Repeatability, and Resolution Explained 3D scanning accuracy describes how closely scan data matches an object's actual geometry and dimensions. It is assessed through local accuracy, volumetric accuracy, stitching accuracy, repeatability, and resolution. What Is Point Cloud Data? Point Clouds, Meshes, and CAD Models in 3D Scanning Point cloud data is an important raw data format in 3D scanning. It consists of discrete 3D coordinate points that describe object surface geometry and support inspection, reverse engineering, modeling, and archiving.

Industrial Applications2 entries

What Is Industrial 3D Inspection? Full-Field Inspection and Deviation Analysis Industrial 3D inspection uses 3D scanning, point cloud processing, and CAD comparison to support dimensional inspection, deviation visualization, quality review, and traceable reporting in manufacturing.

3D Scanning Point Spacing

2026/07/09

3D Scanning Point Spacing

3D scanning point spacing, also referred to as point pitch or point distance, is the linear distance between adjacent discrete 3D coordinate points in a point cloud generated by a 3D scanning system.
3D Scanning Repeatability

2026/07/08

3D Scanning Repeatability

3D scanning repeatability is a metrological performance metric that quantifies the degree of consistency between 3D measurement results obtained when scanning the same object or reference artifact across multiple consecutive trials, under identical operating conditions.
3D Scan Data Post-Processing

2026/06/24

3D Scan Data Post-Processing

3D scan data post-processing refers to the sequence of computational workflows applied to raw 3D scan output (typically unfiltered point clouds, depth maps, or unstructured meshes) captured by industrial 3D scanning systems, to produce accurate, structured, and application-ready 3D assets.
Sources of Error in 3D Scanning

2026/06/24

Sources of Error in 3D Scanning

Sources of error in 3D scanning refer to the full set of systematic, random, environmental, workflow-related, or material-based factors that introduce measurable deviation between the 3D point cloud, mesh, or measurement output of a 3D scanning system and the true geometric dimensions of the physical object being scanned.
Multi-View Alignment in 3D Scanning

2026/06/24

Multi-View Alignment in 3D Scanning

Multi-view alignment in 3D scanning is the core data processing workflow that registers, spatially aligns, and prepares for merging multiple partial 3D point clouds or mesh captures—each collected from a distinct vantage point relative to a target object or scene—into a single, geometrically consistent 3D dataset.
Surface Preparation for 3D Scanning

2026/06/24

Surface Preparation for 3D Scanning

Surface preparation for 3D scanning is a standardized set of pre-scanning processes applied to a physical object’s exterior to enable consistent, accurate, and complete capture of 3D spatial data by optical, laser, or structured light scanning systems.
Exposure in 3D Scanning

2026/06/24

Exposure in 3D Scanning

Exposure in 3D scanning refers to the set of parameters that control the amount of reflected light captured by an optical 3D scanning system’s imaging sensors during a single data acquisition frame.
3D Scanning Depth of Field

2026/06/24

3D Scanning Depth of Field

3D scanning depth of field (DoF) is a core performance metric for industrial 3D scanning systems, describing the range of distances along the scanner’s optical axis within which a target surface can be measured with consistent, specified accuracy and data completeness.
3D Scanning Field of View

2026/06/24

3D Scanning Field of View

3D Scanning Field of View (often abbreviated as FoV) is the calibrated measurable two-dimensional area or three-dimensional volume that a 3D scanning system can capture in a single stationary scan position, without repositioning the scanner, target object, or supporting tracking hardware.
