  • 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.
