摘要
以LabVIEW软件为开发平台,用CCD传感器采集了卷烟圆周横断面图像,以图像处理的方法求出了卷烟圆周长度。介绍了检测系统的组成,然后对所采集的烟支横断面图像,采用灰度变换、中值滤波、阈值分割和形态学开运算等图像处理算法进行了端面图像分析,用LabVIEW软件的图像处理工具包计算出了卷烟圆周的长度像素值,最后通过最小二乘法进行了数学优化,得出了相应的卷烟圆周长度。仿真试验结果表明,该方法检测准确率为94.36%,可以准确检测卷烟圆周长度,有助于提高卷烟产品的质量。
Cigarette circumference was solved with image processing method by using LabVIEW as software platform and CCD as image collection of cigarette circumference. The composition of the detection system was introduced. Collected cross-secti0nal image of cigarette was processed with gray-scale transformation, median filtering, threshold segmentation, morphological opening operation and other image processing algorithms to calculate the circumference of cigarettes. Pixel value of cigarette circumference was calculated by LabVIEW software. Cigarette circumference was corrected by mathematical optimization with least squares method. Simulation results showed that the detection accuracy was 94., 36%; the method can accurately detect the length of cigarette circumference, which is helpful for improving the quality of cigarette products.
