Linear Direct Algorithms for Finding Characteristic Parameters of Circle Parts

In the field of computer vision and image processing, the characteristic parameters such as center coordinates and radius of circle industrial parts often need to be measured. In this paper, three robust, accurate and reliable linear direct algorithms are presented based on the analysis and research of various algorithms in the past, and experimental resalts are given at the end.
