| 摘 要： | 提出了一种基于CCD图像测量的检测方法,该方法将被检圆水准器置于可微倾的工作台上,通过CCD图像系统获取圆水准器的数字图像,并采用随机Hough变换分别提取圆水准器的指标圆和水泡的圆心位置变化量,从而实时检测圆水准器的格值和灵敏度信息。

| Abstract: | 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. |
