Recently, the on-line measurement technique using CCD image is widely used. This paper presents an on-line image measurement method that can be used to measure the diameter of glass rod. Firstly,the images are obtained by CCD capturing. Secondly, based on the characteristics of the image, the image edge of the glass rod is detected. Then the sub-pixel edge detection method is used to determine the edges accurately. Lastly, the beeline fitting method is used to obtain the diameter of the glass rod. The...

Recently, the on-line measurement technique using CCD image is widely used. This paper presents an on-line image measurement method that can be used to measure the diameter of glass rod. Firstly,the images are obtained by CCD capturing. Secondly, based on the characteristics of the image, the image edge of the glass rod is detected. Then the sub-pixel edge detection method is used to determine the edges accurately. Lastly, the beeline fitting method is used to obtain the diameter of the glass rod. The method not only can substitute traditional manual measurement, but also can control the change of the diameter by machine conveniently. The experiment shows that the method can obtain good result.

 近年来,CCD成像在线测量技术得到广泛的应用。提出了一种可应用于玻璃棒直径在线测量的图像测量方法。该方法利用CCD成像技术实时动态获得玻璃棒的在线图像;根据玻璃棒图像的特点,使用图像处理技术提取玻璃棒的轮廓边缘信息;并使用亚像素边缘检测技术精确确定玻璃棒的边缘位置。最后采用直线拟合的方法动态实时获得所测玻璃棒的直径。其方法代替了传统的手工测量,而且易于机器自动反馈控制玻璃棒的直径变化。实验表明此方法达到了理想的测量结果。

Test beam provides single particle beam for different experimentation. 3 multi-wire proportional chambers were used as detectors to describe single particle track of BEPC (Beijing Electron Positron Collider) test beam. The method of dimensional readout centroids of the charge signals induced on the cathodes of the chamber was discussed. The determination of the charge centroid gives two coordinates in one chamber. Beeline fittings of 3 two coordinates' position paints single particle track accurately....
