| 摘要 | Fast and accurate detection of circle is a challenging computer vision problem [1]. This paper takes fully advantages of circle good symmetry to calculate the midpoints of adjacent edge points in the horizontal direction. Based on the sine function reflected by the y coordinate values of midpoints and distance value l from the midpoints to the origin O and the cosine function reflected by the x coordinate values of midpoints and l, the midpoints are projected to parameter space. The main contributions of our work are threefold. 1) The problem of circle detection is formulated as sine curve and cosine curve detection. 2) The abundant phase information carried by trigonometric functions avoids the large amount calculation of Hough Transform. 3) A probabilistic scheme to recognize phase range is applied to circle detection. 1548-7741/Copyright © 2015 Binary Information Press |
