Abstract
Today, circular bubble is tested mainly by manual work that leads to lower efficiency and limited precision. A new testing method based on CCD image system is proposed in which the bubble is laid on an inclinable workbench, and then digital images of the bubble are captured by CCD image system. After the displacement between the center of the bubble and the scale circle is detected through a revised randomized Hough transform, the scale unit and the sensibility of circular bubble can be obtained.
