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. Translucent shells may have false spots on the back. Material optical properties need to be included in calibration and failure conditions
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. Standard parts and contact gauges are crossed to test different surface conditions
