Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods and examples.

[0025] The method of the present invention for calculating transmission flow based on three-dimensional image analysis is composed of the following steps:

[0026] (1) Image acquisition:

[0027] Use an image acquisition machine to collect the contour line of the material on the conveyor belt on the conveyor belt section, such as figure 2 As shown, the image acquisition machine accurately obtains the contour line A'-A-B-C-D-D'-A' on the section of the conveyor belt, and the original shape of the belt section, that is, the area of ​​A-B-C-D-E-F-A is fixed, and A'-D'-E-F is obtained by calculation - the material cross-sectional area of ​​A'; at the same time, the lotus-shaped contour line (such as image 3 )

[0028] The image of the cross-section is collected at night: the beam tube is installed to form a beam with a ...

Abstract

A method for analysing and calculating transmission flow based on three-dimensional image includes collecting three-dimensional image for material fixed on sectional conveying belt, processing image with computer, calculating out flow of granule material on conveying belt, analysing flow data and outputting control signal to ensure conveying device working under the confirmed flow. The device for realizing the method is also disclosed by the present invention.

Description

technical field [0001] The invention relates to the technical field of calculating the flow rate of small particle materials transported by a conveyor belt, in particular to a method and device for calculating the transport flow rate by using three-dimensional image analysis. Background technique [0002] At present, conveyor belts are widely used in long-distance transmission of small particles, such as docks, grain depots, coal mines, and coal-fired power plants. The materials that are conveyed by conveyor belts include yellow sand, grain, and coal. These substances are first lifted by the reclaiming device and temporarily stored in the hopper, and then fall on the conveyor belt, or directly fall on the conveyor belt. Forming, since the speed of the conveyor belt is constant, the shape of the material is directly related to the volume of the small particle material on the conveyor belt. Conveyor belt devices of different specifications have differe...
