AI Technical Summary
Insufficient baseline stability and accuracy in AOI systems lead to errors in detection results, false alarms, and incomparability of indicators, especially severe baseline jumps during equipment maintenance or replacement.
The initial baselines of the camera, lens, and light source are determined by manual calibration, a multidimensional baseline index is established, equipment maintenance events are identified, full or partial reconstruction is performed, regression verification is conducted to confirm whether the new baselines meet production requirements, and the detection logic and alarm mechanism are updated.
It implements baseline version management, ensuring baseline consistency and reliability, avoiding trend breakage, improving detection accuracy, reducing false alarms, and supporting equipment life assessment and production line optimization.
