Suitable applications
Width/height, shape, volume, dimensional sort, robot-pose feed.
Application · Measurement
2D gauging and 3D shape, matched to your tolerances.
Size, form, volume and robot pose. Choose 2D when edges tell the truth; choose 3D when shape and pose variation dominate.
2D vs 3D
Pick the metrology that fits the tolerance story
Empty 3D is expensive. Missing 3D when pose varies is more expensive.
| Need | Usual modality | Watch-out |
|---|---|---|
| Edge / width / presence in plane | 2D gauging | Stable presentation helps |
| Height, volume, free-form shape | 3D profiler / stereo / RGB-D | Calibration discipline |
| Robot grasp pose | 2D or 3D by variation | Closed loop to controller |
| High-speed dimensional sort | Often 2D + lighting | PC-based when throughput bites |
Optics and presentation first
Measurement dies on motion blur, specular highlights and mechanical play. We lock lens, lighting and fixturing before arguing algorithms.
Approach · Integration · Limits
From tolerance to closed loop
We choose 2D or 3D from tolerance and presentation variation, calibrate the optical path, and couple size or pose to PLC or robot, subject to feasibility testing on your parts.
Feasibility
Motion blur, glare and fixturing first, algorithms after.
Delivery
Components & advice, integration, or a complete measurement cell.
Share tolerance and presentation
We will say whether 2D gauging holds, or whether 3D is required.
