Business tasks and intended output
- target audience
- Laser diode packaging: spot position on target surface
- pseudo output
- XY difference before and after curing
- Applicable conditions
- The curing and thermal deformation of the tooling itself requires a reference channel
- priority
- Prioritize verification. The two-dimensional difference before and after curing can be verified first without the need for complete three-dimensional inversion.

Current capabilities and capabilities to be supplemented
Reusable modules
Existing modules can be used as hosts
Existing light point positioning, quality diagnosis or statistical modules can be used as the main calculation basis; ROI, calibration, threshold and interface verification still need to be completed by device.
Gaps in this scenario:ROI, ruler/plane calibration and reference point definition are required; only the two-dimensional position of the target surface can be directly observed. The curing and thermal deformation of the tooling itself requires a reference channel. Pixel grayscale and optical power are calibrated separately
Route-level gaps:Requires ROI, ruler/plane calibration and reference point definition; can only directly observe the two-dimensional position of the target surface
"Reusable modules" only describe the relative development volume and do not constitute a commitment to accuracy, tempo, stability or delivery time.
Verification methods and acceptance prerequisites
Test independently with a two-dimensional displacement stage and a fixed reference point, reporting center error P95, missed detections and false detections. Independent beam analyzer and temperature control/current recording cross-reference
