摘　　要：针对烟草企业广泛存在的水松纸透气度检测问题,本文提出了一种基于数字图像处理和最小二乘拟合(Least Squares Fitting,LSF)的检测方法,用于对打孔水松纸进行在线检测。首先,采用数字图像处理技术提取测量区域内的打孔水松纸孔面积;其次,利用最小二乘拟合方法建立孔面积与打孔水松纸透气度之间的拟合模型,进而使用该模型计算透气度。基于实际生产数据的测试结果验证了所提方法的有效性。In this paper, a method based on digital image processing and least square fitting is proposed for solving the tipping paper porosity on-line measuring problem, which widely exits in tobacco enterprises. Firstly, the digital image processing technology is selected to calculate the total area of all the holes in the measurement area of the perforated tipping paper. Secondly, the least squares fitting method is utilized to build a fitted model between the holes＇ area and the tipping paper porosity, and then the built model is used to calculate the porosity. The test results of the actual production datum show that the proposed method is effective.
