LED-based multi-view conveying belt longitudinal tearing image acquisition method

Abstract

The invention discloses an LED-based multi-view conveying belt longitudinal tearing image acquisition method. The LED-based multi-view conveying belt longitudinal tearing image acquisition method involves two line-scan digital cameras, a gigabit switch, an image acquisition and processing device, an LED light source and a PC; and the line-scan digital cameras are connected with the image acquisition and processing device through the gigabit switch, and the image acquisition and processing device is connected with the PC through the gigabit switch. The two line-scan digital cameras are arrangedbetween an upper belt section and a lower belt section of a conveying belt. The LED-based multi-view conveying belt longitudinal tearing image acquisition method is characterized in that the installing positions of the cameras are determined according to the structural characteristics of the conveying belt and related components thereof as well as the image shooting requirements of the line-scandigital cameras, and thus the effect that images acquired by the two cameras are spliced and processed through the image acquisition and processing device so as to form information of a complete imageof the lower surface of the upper belt section of the conveying belt is guaranteed. The LED light source is used for supplementing image acquisition equipment with light, so that the images are clear. By means of the LED-based multi-view conveying belt longitudinal tearing image acquisition method, the complete and clear surface images of the conveying belt can be acquired, and a base is laid forimprovement on accuracy and real-time performance of monitoring of conveying belt longitudinal tearing faults.

Description

technical field [0001] The invention belongs to the field of longitudinal tearing monitoring of conveyor belts, and in particular relates to a multi-viewpoint conveyor belt longitudinal tearing image acquisition method based on an LED light source. Background technique [0002] In the process of conveying materials, the conveyor belt often has longitudinal tearing failures. The main reasons include being scratched by foreign objects or obstacles such as scrap steel or coal gangue, improper installation and adjustment of the belt conveyor, and unbalanced load caused by the incorrect blanking position at the transfer point. evenly etc. If the fault is not detected and dealt with in time, a longitudinal tearing accident will occur, resulting in production stoppage, loss of transportation materials, equipment damage and casualties, which seriously affects safe production. At present, the longitudinal tearing monitoring method of conveyor belt based on machine vision technology ...

Problems solved by technology

[0002] Conveyor belts often have longitudinal tear failures during the process of conveying materials. The main reasons include scratches by foreign objects or obstacles such as scrap iron and steel or coal gangue, improper installation and adjustment of belt conveyors, and improper loading caused by incorrect blanking positions at transfer points. evenly

If the fault is not detected and dealt with in time, a longitudinal tear accident will occur, resulting in production stoppage, loss of transported materials, equipment damage and casualties, seriously affecting safe production

At present, the conveyor belt longitudinal tear monitoring method based on machine vision technology can accurately and quickly monitor the longitudinal tear fault of the conveyor belt. In the conveyor belt longitudinal tear fault monitoring scheme based on machine vision technology, how to quickly collect the complete and clear image information of the conveyor belt surface during the operation of the conveyor belt has become a key factor affecting the longitudinal tear fault monitoring of the conveyor belt
