AI Technical Summary

Technical Problem

In existing automated carbon fiber prepreg laying technology, the accumulation of visual measurement errors caused by the dynamic changes in the optical properties of the prepreg surface affects product quality and causes economic losses. Furthermore, existing systems have difficulty distinguishing between measurement drift and actual physical deviation, and cannot perform accurate calibration or compensation.

Method used

By acquiring tiling process parameters and visual features, a correlation is established to determine whether the deviation originates from measurement drift or actual physical deviation, and corresponding calibration or compensation operations are performed, including visual measurement result compensation or physical correction instructions.

Benefits of technology

It effectively distinguishes the source of deviation, avoids invalid calibration or cumulative error caused by misjudgment, and improves product quality and production efficiency.

Abstract

The invention provides a carbon fiber prepreg paving real-time positioning calibration method and system. The method comprises the following steps: acquiring paving process parameters which influence the optical characteristics of the surface of a prepreg strip; collecting visual information of the edge of the prepreg strip, and extracting visual characteristics reflecting the optical characteristics of the surface of the prepreg strip from the visual information; presetting an association relationship between the paving process parameters and the visual features; receiving a visual measurement result indicating that the paving position of the prepreg strip has deviation; according to the paving process parameters, the visual features and the incidence relation, the source of paving position deviation is judged; and executing calibration or compensation operation according to the judgment result of the deviation source. According to the invention, invalid calibration or accumulative errors caused by misjudgment can be avoided.
