AI Technical Summary
Traditional methods for inspecting C-shaped parts suffer from problems such as image breakage, geometric distortion, and low image quality, especially on complex workpieces with significant bending features or C-shaped cross sections. This leads to a decrease in the coherent representation of defect distribution and the reliability of inspection results.
By acquiring planned path points, ultrasound A-scan data, and TCP point data, a parameterized geometric model is constructed using principal component analysis. The three-dimensional point cloud is projected onto the surface of the model and unfolded into a two-dimensional plane to establish a mapping relationship between spatial points and image pixels, thereby generating a C-scan image.
It achieves continuity and accuracy of C-scan images, avoids image breaks and geometric distortions, improves the intuitiveness and accuracy of defect interpretation, and ensures the integrity and reliability of image information.
