Coal conveyor monitoring management system based on stereoscopic vision

Abstract

The invention discloses a coal conveyor monitoring management system based on stereoscopic vision. The coal conveyor monitoring management system comprises a coal conveyor and one or more line laser binocular stereoscopic cameras arranged above the coal conveyor. A visual processor of each line laser binocular stereo camera comprises a stereo visual processing module, a coal flow monitoring module, a foreign matter detection module and a conveyor position detection module, and the stereo visual processing module is used for processing a laser line image by using a binocular visual processing algorithm to obtain front three-dimensional information of a conveyor belt and three-dimensional information of a coal flow on the conveyor belt; the coal flow monitoring module is used for acquiring coal flow monitoring information according to the three-dimensional information of the coal flow on the conveying belt and the reference surface three-dimensional information; the foreign matter detection module is used for detecting large objects according to the three-dimensional information of the coal flow on the conveying belt and a set area threshold value; and the conveyor position detection module is used for calculating position offset information of the conveyor according to the three-dimensional information of the coal conveyor and the datum plane three-dimensional information. The coal conveyor monitoring management system based on the stereoscopic vision can synchronously complete various detections with high precision, and is high in automation degree.

Description

technical field [0001] The invention relates to the technical field of coal transportation management, in particular to a coal transportation machine monitoring and management system based on stereo vision. Background technique [0002] my country is a country with large coal resources and a large coal consumption country. Coal, as the main primary energy in my country, accounts for more than 60% of the total primary energy consumption in my country. Therefore, the country attaches great importance to the mining and processing of coal. At present, during the transportation of mined coal on the transport plane, the degree of automation is low in the detection of large coal / foreign objects, and people are still used to stare at the equipment to see if there are large lumps of coal / foreign objects; for the detection of coal flow, often Ignoring the gap between the belt and the idler, it is considered that the belt is completely in contact with the idler, resulting in a low calc...
