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:Point sequence numbering, local ROI, crosstalk and occlusion processing are required; A108 only matches by distance in the same coordinate system. Perspective distortion is calibrated first. The lattice front-end can be reused; three-dimensional depth and absolute efficiency must be built separately.
Route-level gaps:Point sequence numbering, local ROI, crosstalk and occlusion processing are required; A108 only matches by distance in the same coordinate system
"Partially reusable" only describes the relative development volume and does not constitute a commitment to accuracy, tempo, stability or delivery time.
