The ore fragment size on the conveyor belt of concentrators is not only main index to verify crushing process, but also affects production efficiency, operation cost and even safety mine. In order get fragments belt, image segmentation method a convenient fast choice. However, due influence dust, light uneven color texture, traditional methods are prone oversegmentation undersegmentation. solve these problems, this paper proposes an model called RDU-Net (R: residual connection; DU: DUNet),...
Structured light vision fails to detect the high-temperature objects up 1700 °C because projected patterns are drowned by strong self-emitted radiation of objects. For this problem, signal enhancement and extraction laser carried out in paper. Signal consists two steps. The first step involves physical spectrum selective source filtering optical filter. Theoretical analysis finds that, working wavelength should be short, pass-band width transmittance stop band filter small. second...
Camera calibration is a necessary step in 3D computer vision, and the accuracy of largely dependent on localization precision control points patterns. However, sub-pixel methods for commonly used two types points, corners squares centers circles, are markedly different from each other. In this work, we propose unified approach to points. The derived theoretical analysis consists closed-form solution, followed by algorithms practical implementation. Both synthetic dataset real experiments...
Oxidative hair dyes consist of two components (I and II) that are mixed before use. Aromatic amines in component I their reaction with hydrogen peroxide after mixing them II have been primary concern. In addition, vitro genotoxicity assays still required for the approval final products oxidative China, substance dye causes high rate positive results tests, especially Ames test, has not fully elucidated. this study, we analyzed formulation 55 different from 7 color series performed tests...
Abstract Binocular vision system calibration is extremely important in three-dimensional (3D) measurement. During the process, establishment of an appropriate objective function has a direct impact on accuracy. For common two-dimensional (2D) methods, differences 2D and 3D measurement coordinate systems result loss Furthermore, for newly proposed epipolar constraints pixel reconstruction errors physical space need to be balanced by weights, resulting uncertainties results. To address these...
Abstract Heavy-duty trucks in open-pit mines are of huge size and blind areas, so it is difficult for drivers to see other vehicles around the areas. In addition, due dullness transportation mines, prone distraction phenomena, collisions between occur from time time. existing technologies, such as radar infrared ranging, detect on side bend at bend, vulnerable dust weather, resulting false alarm. Aiming above problems, a collision prevention warning scheme heavy truck open pit mine based RBF...
