Need to add new core
Projected point matching as a depth front end
For the structured light depth module, the three-dimensional positioning of the lattice is used as the observation route, and the pseudo output point corresponds to the effective point mask. The page is for project evaluation and does not mean that the development has been completed or has been accepted on site.

Current capabilities and capabilities to be supplemented
Need to add new core
Need to add core computing
Light point extraction can only be used as an observation front-end, and core capabilities such as three-dimensional reconstruction, closed-loop control, wavefront or physical quantity inversion need to be developed and verified separately.
Gaps in this scenario:Three-dimensional correspondence, PnP/triangulation, SE(3) external parameters and hand-eye calibration need to be added; A42 is only two-dimensional. Deep triangulation and external reference cores need to be added. The lattice front-end can be reused; three-dimensional depth and absolute efficiency must be built separately.
Route-level gaps:Three-dimensional correspondence, PnP/triangulation, SE(3) external parameters and hand-eye calibration need to be added; A42 is only two-dimensional
"New cores required" only describes the relative development volume and does not constitute a commitment to accuracy, tempo, stability or delivery time.
