Zusammenfassung: | The existing coal stacking identification method of belt conveyor has problems of false trigger alarm and high cost. In order to solve the above problems, a coal stacking identification method of belt conveyor is proposed. The method uses infrared structured light technology to quickly reconstruct the coal flow surface of belt conveyor.Firstly, the depth map of the coal stacking is obtained by using infrared structured light technology. Secondly, the depth map is mapped to a point cloud map, and the point cloud data is used to construct a convex quadrilateral network. And the convex quadrilateral network is triangulated by the approximate Delaunay subdivision method to complete the reconstruction of the coal stacking surface.Finally, according to the distance from the triangle vertex to the camera and the proportion of the triangle area whose vertex distance is less than the threshold to the total area, it is determined whether there is a coal stacking accident.The approximate Delaunay subdivision method repl |
