Precision tells you whether repeated scans agree. A scanner can capture a crisp, repeatable model that is still dimensionally wrong, so choose by the object, required tolerance, work volume, and test evidence—not by resolution alone.
Accuracy, precision, and resolution answer different questions
| Measure | What it answers | Why it matters on a project |
|---|---|---|
| Accuracy | How close a measured dimension is to its true value. | Determines whether the dimension is close enough for the project’s tolerance. |
| Precision | How consistent repeated measurements are. | Indicates whether the scanning workflow produces repeatable results. |
| Resolution | How small a detail the system can distinguish. | Helps determine whether grooves, edges, or other small features appear in the captured geometry. |
| Volumetric accuracy | How dimensional performance behaves across a measurement volume. | Helps assess whether performance remains suitable across the object’s size and span. |
These terms are not interchangeable. Resolution describes detail capture, not dimensional correctness. Precision describes consistency, not correctness: repeated scans can agree with one another and still differ from the true dimensions. SHINING 3D explains these distinctions and the point-versus-volumetric accuracy distinction in its scanner accuracy guide; its examples are manufacturer material, not a guarantee for other scanners or setups.

Why one accuracy figure may not predict your results
Before comparing an advertised accuracy number, find out what it measures. A point-level figure and a volumetric result describe different aspects of performance. A distance-dependent volumetric specification can accumulate error across a length, so a result measured over a short span may not describe how well the system handles a larger object.

Ask what measurement range was tested, which method and standard were used, and whether the figure applies to the scanner configuration you will use. The test range and setup should resemble the actual object and scanning process; a figure without that context is difficult to apply to a project tolerance.

Standards help, but test scope still matters
NIST’s 2019 review notes that structured-light scanners vary in sensor configuration, projected patterns, work volume, point density, triangulation angle, and targets. It warns that test conditions that differ from real applications can lead to poor instrument-selection decisions. Read the review, “Sources of Errors in Structured Light 3D Scanners”.
A standard-based result is useful evidence, not a universal promise for every object or setup. NIST’s 2024 study compared length-test sensitivity in VDI/VDE 2634-2 and ISO 10360-13 for structured-light systems. In that study, ISO tests were more sensitive to system model parameters, but even those tests did not detect every parameter with high sensitivity. The finding is specific to the study; it does not establish that one standard guarantees better results in all applications. See NIST’s study published April 29, 2024.

If a vendor cites a standard, request the actual certificate or report. Check the standard and part, tested configuration and range, laboratory, and stated result. SHINING 3D’s guide discusses VDI/VDE 2634 parts and ISO 10360-13; what matters for your decision is whether the document’s scope resembles your intended work.

Match scanner performance to the part and tolerance
Start with the project’s requirements, not the scanner’s headline specification. For a small feature, detail capture may be the limiting factor. For a long part or dimensional inspection, performance over the relevant span and the tolerance budget may matter more. Work volume, surface and target conditions, and scan setup can also affect how well published evidence transfers to your workflow.

- Visual digitizing: Decide what details must be visible in the model; do not treat a high-resolution claim as proof of dimensional accuracy.
- Reverse engineering: Consider both whether the geometry preserves the features you need and whether measured dimensions are sufficiently close for the intended design work.
- Dimensional inspection: Compare documented performance over the relevant measurement range with the project tolerance, and consider the other contributions in the workflow rather than treating scanner accuracy as the entire tolerance budget.
When reviewing a structured-light scanner workflow, check whether it relies on targets or markers and whether the actual surface and geometry suit that setup. If dimensional inspection is involved, ask what verification or 3D scanner calibration documentation applies to the specific configuration and intended use; the available evidence here does not establish a provider or service recommendation.

A practical comparison checklist
- Record the job requirements: Write down the object’s dimensions, smallest feature to retain, and required tolerance.
- Set the primary goal: Identify whether the work is visual digitizing, reverse engineering, or dimensional inspection.
- Clarify the accuracy claim: Ask what the published figure represents—point or volumetric performance—and how it was tested.
- Check the test scope: Compare the tested range and scanner configuration with the object and planned scanning setup.
- Request the evidence: Obtain the applicable report or certificate and confirm its standard, part, configuration, range, laboratory, and stated result.
- Evaluate detail separately: Compare resolution with the smallest feature the project needs to preserve; do not use it as a substitute for dimensional accuracy.
- Check the workflow fit: Confirm that surface, geometry, and any targets or markers suit the proposed scanning process.
