Imaging input and algorithm routing

Imaging and device conditions

By fixing the laser emission axis and the receiving camera baseline, separable light spots can be formed on the target surface. Processing light is sampled attenuated, or verified coaxial, low-power guided light

TRI·Point laser triangular displacement

By fixing the laser emission axis and the receiving camera baseline, the target surface can form separable light spots.

  • A100First-order sensitivity uncertainty propagation
  • A101Adaptive threshold laser spot grayscale centroid

Current capabilities and capabilities to be supplemented

Partially reusable

Requires calibration, synchronization or integration

The light point detection front-end or timing statistics module can be reused, but the project still needs to add geometric calibration, time synchronization, motion compensation or equipment system integration.

Gaps in this scenario:It is necessary to add point laser ray intersection or one-dimensional nonlinear distance calibration adaptation; A97 only has a linear area, and A21 is a laser plane interface. Reflective workpieces need to be protected against multipath. The guide light position represents the machining beam only within the coaxial verification range

Route-level gaps:It is necessary to add point laser ray intersection or one-dimensional nonlinear distance calibration adaptation; A97 is only in the linear area, and A21 is the laser plane interface

"Partially reusable" only describes the relative development volume and does not constitute a commitment to accuracy, tempo, stability or delivery time.

Verification methods and acceptance prerequisites

Use gauge blocks and stages to cover range and surface conditions and independently report physical error, repeatability, and speckle effects. Cross-reference with processed test piece, beam analyzer and positioning table
