Sandpaper is an indispensable and important article in industrial production and daily life. However, due to technological reasons, not all sandpaper can meet the standard. At present, in the traditional industrial production, in order to improve the quality of sandpaper, the usual way to identify the problem sandpaper is human eyes. Due to the influence of personnel factors, the accuracy and reliability of this way are low, and the production cost is high and the efficiency is low. Therefore, we designed an automatic detection system of sandpaper defects based on digital image processing technology, which can effectively improve the recognition rate of defective sandpaper, reduce the production cost and improve the production efficiency.

“…Non-contact measurement technology is widely used, especially for the large-scale measurement of workpieces, such as propeller blades [ 1 ], antenna reflectors [ 2 ], cabin capacity [ 3 , 4 ], vertical metal containers, etc. This technology can realize long-distance, high-precision and fast measurement for large-scale objects, which avoids interfacial contact and possible deformation in the measurement.…”

The calibrator is one of the most important factors in the calibration of various laser 3D scanning instruments. The requirements for the diffuse reflection surface are emphasized in many national standards. In this study, spherical calibrator and plane calibrator comparative measurement experiments were carried out. The black ceramic standard sphere, white ceramic standard sphere, metal standard sphere, metal standard plane, and white ceramic standard plane were used to test the laser 3D scanner. In the spherical calibrator comparative measurement experiments, the results indicate that the RMS of the white ceramic spherical calibrator with a reflectance of approximately 60% is 10 times that of the metal spherical calibrator with the reflectance of approximately 15%, and the RMS of the black ceramic spherical calibrator with reflectance of approximately 11% is of the same order as the metal spherical calibrator. In the plane calibrators comparative measurement experiments, the RMS of the flatness measurement is 0.077 mm for the metal plane calibrator with a reflectance of 15%, and 2.915 mm for ceramic plane calibrator with a reflectance of 60%. The results show that when the optimal measurement distance and incident angle are selected, the reflectance of the calibrator has a great effect on the measurement results, regardless of the outlines or profiles. Based on the experiments, it is recommended to use the spherical calibrator or the standard plane with a reflectance of around 18% as the standard, which can obtain reasonable results. In addition, it is necessary to clearly provide the material category and surface reflectance information of the standard when calibrating the scanner according to the measurement standard.
