Abstract

On-line diameter measurement is essential in producing round extruded products, as defects can lead to significant losses in production effort and resources. Traditional mechanical sampling inspections have been replaced by contact-free, inline measurement systems that continuously monitor diameter along the production line. While these systems effectively detect circular shapes and measure radius, they often struggle with position artifacts, leading to measurement errors. To achieve improved accuracy and precision, it is crucial to incorporate considerations of non-orthogonality into the image processing algorithm. Methods such as feature extraction and image segmentation are utilized to identify abnormalities. Additionally, integrating machine learning models enables real-time quality assessment and automated decision-making. However, the Hough Circle Transform, though effective for detecting circles, has limitations, including sensitivity to noise, computational intensity, and challenges in identifying occluded or imperfectly circular objects. This paper proposes a novel method to measure the diameter of a circle based on its eccentricity. The method involves analyzing captured images for edge detection and eccentricity measurement at various angles relative to the camera lens. Additionally, it establishes a relationship between the line-of-sight angle, the eccentricity of the perceived ellipse, and the diameter of the actual circle. The results obtained are compared with those achieved using the Hough Circular Transform (HCT), demonstrating improved accuracy with the proposed method. This study presents a practical solution for enhancing quality control in the mechanical industry, addressing current needs with an inclusive and error-resistant approach.
