Partially reusable
Two-dimensional calibration of projected coordinates and camera coordinates
For the micro-projection module, the two-dimensional command/target coordinate calibration is used as the observation route, and the full field of view coordinate residual is planned to be output. 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
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:Calibration acquisition, coordinate definition and verification are required; two-dimensional empirical mapping does not represent any three-dimensional or robot calibration. Imaging distortion may exceed the quadratic model. Laser spots used for testing do not represent full image quality
Route-level gaps:Calibration acquisition, coordinate definition and verification are required; two-dimensional empirical mapping does not represent any three-dimensional or robot calibration
"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
Separate calibration points and set-out points to check edge, back-and-forth, temperature and repeated clamping errors. Standard image plane, angle table and imaging test chart are separately accepted
