AI Technical Summary
Traditional manual methods for inspecting steel ring quality are inefficient and inaccurate, making it difficult to meet the stringent quality control requirements of modern industrial production. Existing equipment and methods are complex, time-consuming, and unable to accurately detect key parameters such as out-of-roundness.
The method employs a contour scanner and a remote smart terminal working together. PolyWorks software is used for coordinate positioning and feature coordinate system establishment. By combining covariance matrix analysis and ICP algorithm, normal vectors and curvature weights are introduced to construct a defect point matching map. The Hungarian algorithm is used to solve for the maximum weight matching, and an extreme value extraction algorithm is combined for rapid detection.
It achieves high-precision, high-speed, and automated steel ring quality inspection, reducing the inspection cycle from 30 minutes to 5 minutes, with accuracy stabilized within 0.05mm. It is suitable for automated production lines, reducing the cost of technical transformation.
