AI Technical Summary
Existing technologies rely on human experience in scraping and testing, resulting in a lack of objective consistency in test results and difficulty in effectively identifying high points of large-area adhesion and high points under environmental interference.
A visual detection method based on distance field high point recognition is adopted. The brightness and blue-yellow components are extracted by transforming the Lab color space, a composite scoring function model is constructed, and the high point region is divided by combining the Euclidean distance field and adaptive dynamic threshold segmentation. High points are then filtered by roundness and aspect ratio to achieve accurate high point recognition.
It improves the accuracy and consistency of high point identification, reduces manual intervention, effectively separates adhered high points, and improves detection efficiency and lubrication properties.
