Abstract
Digital image processing and analysis technology has been rapidly developed and widely used in today's digital information age, and has shown an important position. Digital image processing technology mainly includes image binarization, edge detection, contour extraction and thread geometric parameters calculation. At the same time, the points on the boundary are sorted, and the transition points in the boundary feature points are detected. Finally, the point boundary polygon is constructed. In the feature description stage, the local features are described, and the image is digitally processed in the computer to obtain the contour of the thread, thereby calculating the geometric parameters of the thread and improving the fidelity of the image quality, which is generally called image restoration technology. Feature detection not only has good matching performance, but also has a lower dimension, which is very beneficial to improve the matching speed of image features. Image enhancement techniques will be used primarily in the pre-processing of tapered threads to improve image quality.
