| 摘 要： | 确认旋转中心是工业CT系统必然遇到的问题。本文提出对薄圆筒模体的切片图像自动识别,通过随机Hough变换识别薄圆筒模体的圆心位置和半径,从而计算出当前圆心与实际圆心的差别,据此可以计算出需要矫正的尺寸,减少确认旋转中心的复杂度并增加可靠性。 |
| 关 键 词： | 工业CT 模体 Hough变换 旋转中心 |

| Abstract: | Rotation Center Determination is one of the basic problems in CT system integration.This paper proposed an automatic method to decide rotation center by Hough Transform with thin cylinder phantom.Hough Transform can provide position and radius of cylinder and also the difference of actual radius of cylinder,the radius of the cylinder,and the difference of the actual radius of the cylinder.With this difference,we can determine the rotation center of CT system. |
| Keywords: | industrial CT phantom Hough transform rotation center |
