Abstract

The invention relates to a belt coal flow visual identification method. The method comprises the following steps: projecting lattice structure light onto a coal conveying belt, and forming lattice light spots on the coal conveying belt and coal materials; collecting image information on the coal conveying belt under irradiation of the lattice structure light; extracting lattice light spot features in the image information to form lattice cloud information; performing three-dimensional reconstruction according to the lattice cloud information to obtain a three-dimensional model of the coal materials on the coal conveying belt in a preset time period; performing slicing processing on the three-dimensional model at a preset interval to obtain slice images; projecting the slice images to a two-dimensional coordinate system; estimating weight of the coal materials corresponding to the single slice image according to the area of the slice images and the preset interval; and accumulating all slices to obtain a weight estimation value of the coal materials in the preset time period, and calculating flow information of the coal materials in unit time according to the weight estimation value. According to the belt coal flow visual identification method provided by the invention, a more accurate identification result can be obtained.

Description

technical field [0001] The invention relates to an image recognition method, in particular to a visual recognition method of belt coal flow. Background technique [0002] At present, the belt conveyor is the main means of ground and underground coal transportation, and the belt conveyor is also the main equipment for coal production and transportation. In order to accurately detect the amount of coal conveyed, the coal flow detection on the belt conveyor is also an important link in coal production or transportation operations. At present, the means of detecting the coal flow on the coal conveyor belt mainly focus on two aspects, one is realized through the coal flow sensor, and the other is detected through the method of visual recognition. However, the inventors have found that both of the current implementation methods have the disadvantage that the detection accuracy is easily affected by the environment, which needs to be improved. Contents of the invention [0003]...
