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. Contact resistance is measured separately. The camera only covers the frequency bands supported by its sampling and exposure
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.
