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:It is necessary to add new point triangulation intersection, scanning coordinate fusion, surface reconstruction and shape and position evaluation; A41 only fits existing three-dimensional points. Edge mixed pixels need to be removed. It is necessary to complete the definition of datum and tolerance before judging OK/NG.
Route-level gaps:It is necessary to add new point triangulation intersection, scanning coordinate fusion, surface reconstruction and shape and position evaluation; A41 only fits existing three-dimensional points.
"New cores required" only describes the relative development volume and does not constitute a commitment to accuracy, tempo, stability or delivery time.
Verification methods and acceptance prerequisites
Use a known step/contour sample to perform a blind test with a CMM or profiler to verify the missing area and scanning step distance. Independent control of gauge block, profiler or three coordinates
