Joint external parameter study of camera and emission axis
For the robot camera laser combination, the lattice three-dimensional positioning is used as the observation route, and the intended output point corresponds to the geometric residual. 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. The hand-eye and point-ray calibration cores need to be added. Two-dimensional target surface observation and complete three-dimensional robot calibration are defined 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.
