AI Technical Summary

Technical Problem

Existing webbing quality inspection methods are easily affected by mechanical vibration and tension fluctuations on high-speed production lines, resulting in inaccurate width measurements. Furthermore, surface defect detection is independent of geometric dimension measurement, affecting the accuracy of quality judgment.

Method used

By establishing a detection coordinate system, dynamically selecting centripetal nodes to construct a double-centered ring domain, generating chordal subdivision reference lines along the webbing length direction, performing equidistant affine derivation and confidence coupling calibration, and combining spatial correlation analysis between the defect area and the edge baseline to generate corrected width detection values ​​and defect distribution information.

Benefits of technology

It improves the dynamic accuracy and stability of webbing width measurement, avoids misjudgment based on a single abnormal feature, realizes refined grading of webbing quality, and improves the consistency and accuracy of detection.
