摘要: 在无损探伤自动检测线上,为了记录每根管材的有关参数,需在管端进行打号、读号处理。详细介绍了管号识别系统中关键的图像预处理二值化算法。该算法称之为Stamp算法,是在分析Phototshop图像处理软件Stamp滤镜功能的基础上,结合自动检测线上采集图像的特点而得出的。Stamp算法还可以用于车辆牌照自动识别的二值化处理等领域。

Abstract: To record the correlative parameters of each tube in nondecstructive testing automatic pipeline,the printing number and reading number at the end of the tube is needed.A key image preprocessing binarizatation algorithm in tube number reader system is introduced.The algorithm is called after Stamp,which is based on Stamp filter in Photoshop and video camera collecting characteristic image.It is still applied to image preprocessing in automatic vehicle license plate recognition et al.
