摘要: 为了实现卷烟包装尺寸的非接触式测量,提出了一种基于双线结构光的烟包尺寸测量方法:采用成一定交角的双色线结构光对样品进行旋转扫描;使用CCD相机获取每个旋转角度下结构光在烟包上的反射图像;利用世界坐标系、结构光坐标系和图像坐标系的转换关系,从结构光的形变特征反演得到烟包的表面形貌,并从获取的3D点云中拟合出相应的外切长方体尺寸.实验结果表明,该方法的测量精度和标准偏差能够满足实际检测需求,有效地提高烟包和条包尺寸的测量效率和准确性,为卷烟包装尺寸测量提供了一种有效的自动化测量方法.

Abstract: In order to achieve the non-contact measurement of cigarette packing size, a size measuring method based on dual structured light was proposed.The dual structured light which crossed with a certain angle was used to scan the cigarette packing.The CCD camera was used to obtain reflection images of structured light in each rotation angle on cigarette packing.According to the conversion relationship between world coordinate system, structured light coordinate system and image coordinate system, the surface characteristics of the case was calculated from the deformation feature of structured light.Then, the size of the circumscribed cuboid from 3D point cloud was calculated.The experimental results showed that the measuring accuracy and the standard deviation of the method could meet the actual demand for testing,improving the measurement efficiency and accuracy effectively,providing an effective method of automatic measurement for cigarette packing size measurement.
