Imaging input and algorithm routing

Imaging and device conditions

Linear response imaging, fixed attenuation and background acquisition avoid saturation and ROI truncation. Optical path sampling or target collection before welding, strong process light requires filtering and triggering

BM · Spot shape and relative distribution

Linear response imaging, fixed attenuation and background acquisition to avoid saturation and ROI truncation

  • A101Adaptive threshold laser spot grayscale centroid
  • A105Laser spot second moment and main axis diameter
  • A106Laser spot surrounding energy diameter
  • A107Laser spot quality and usability diagnostics

Existing algorithmic evidence:A101–A112 only complete analytical synthesis spot and controlled geometry verification; see laser_spot_benchmark.json

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:Pixel scale, background subtraction and dynamic range verification required; grayscale integration is not watts or joules. The impact of the wedge angle of the protective mirror must be calibrated. Only the incident beam/guide beam status is described, and the internal quality of the weld needs to be independently inspected.

Route-level gaps:Pixel scale, background subtraction and dynamic range verification required; grayscale integration not watts or joules

"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

Verify center, width and cutoff separately against a stand-alone beam analyzer or known spot pattern. Beammeter and weld specimen cross-section/process log cross-check
