Measurement
Dimensional measurement and position inspection solution
Use calibration, sub-pixel edges, geometric fitting and stable imaging to turn vision results into measurable, acceptable and traceable data.
Object
Dimensions
Hole positions, margins, spacing, angles, contours and assembly positions.
Method
Calibration
Convert image coordinates into usable dimensions and deviations.
Output
Values
Dimensions, deviation, tolerance alarms and quality records.
Scenarios
For stations that need quantified dimensions and positions
Measurement projects must consider accuracy, repeatability, mechanical stability and consistency with gauges.
02
Contour and angle inspection
Inspect edges, outer dimensions, angles, missing material and assembly position.
03
Online quality records
Output dimensions, OK/NG, image evidence, batch and tolerance alarms.
System
Measurement needs imaging, calibration and mechanical stability
Vision measurement is not simple pixel reading. It combines lenses, calibration, fixtures, lighting and repeatability validation.
01
Cameras, lenses and calibration
Select area cameras, telecentric lenses or line-scan routes and perform pixel scale and distortion correction.
02
Edges and geometry
Use sub-pixel edges, line / circle fitting, geometry and tolerance rules to output measurements.
03
Quality records and alarms
Store dimensions, trends, images, batches and out-of-tolerance alarms for quality traceability.
Process
Work backward from measurement target to imaging and mechanics
Define accuracy and repeatability before choosing camera, lens, field of view and fixtures.
01
Measurement definition
Confirm objects, accuracy, repeatability, takt time, gauge comparison and acceptance method.
02
Imaging and calibration
Define field of view, resolution, lens, lighting, calibration and workpiece fixation.
03
Algorithms and tolerance rules
Build edge extraction, geometric fitting, dimensional calculation, OK/NG and alarm rules.
04
Repeatability validation
Confirm stability through repeated measurement, gauge comparison and line-speed tests.
Deliverables
Make measurements comparable, acceptable and traceable
Measurement delivery should explain calibration, formulas, tolerance rules and data records clearly.
01
Measurement plan and calibration guide
Field of view, pixel scale, calibration steps and maintenance notes.
02
Tolerance rules and report fields
Dimensions, deviations, limits, OK/NG, batch and statistics fields.
03
Repeatability and acceptance records
Repeatability tests, gauge comparison and on-site acceptance records.
FAQ
Measurement projects need accuracy boundaries first
Camera resolution, lens, calibration, fixture and environment all affect measurement stability.
What accuracy can vision measurement achieve?
It must be evaluated by field of view, resolution, lens, workpiece stability and method. Accuracy cannot be promised without site conditions.
Is a telecentric lens always required?
High accuracy, height variation or perspective-sensitive scenarios usually require telecentric lens evaluation.
How does it align with manual gauges?
Define gauge, measurement datum, fixture state, calibration and statistics first, then run repeatability validation.
Measurement Review
Confirm accuracy and acceptance before measurement projects
Send drawings, accuracy requirements, product photos and current gauge method so we can evaluate feasibility.
