Embodiment Construction
[0031] Such as figure 1 As shown, the present invention installs a camera 4 directly above the conveyor belt 1, and the camera monitors the conveyor belt and the idler roller 2 and the support 3 of the conveyor belt support device in real time, and transmits the video signal to the image processing device through the optical fiber 6 for further processing. Analytical processing, image processing device adopts computer 5. The field of view of the camera 4 can completely cover the area of the conveyor belt and the supporting device, and the centerline of the camera is located on the longitudinal centerline of the conveyor belt 1 . The conveyor belt support device is also referred to as the support device herein.
[0032] The method for measuring the instantaneous relative conveying volume of a conveyor belt based on monocular vision in the present invention includes three aspects.
[0033] 1. Estimate the conversion function of the deformation of the support device and the r...

The invention provides a method for measuring instantaneous relative conveying quantity of a belt conveyor based on video analysis, which comprises the following steps of: (1) monitoring a conveying belt and a conveying belt supporting device in real time by a camera, acquiring a video single-frame image by the camera, and transmitting the image to an image processing device so as to identify theselected conveying belt supporting device in the image and calculate the deformation quantity of the conveying belt supporting device; (2) determining the relative conveying quantity of the materialscarried by the conveying belt according to the relative conveying quantity calculation function and the deformation quantity of the conveying belt supporting device. According to the method for measuring instantaneous relative conveying quantity of the belt conveyor based on video analysis, the deformation quantity of the supporting device is monitored and detected through a monocular camera, andthe conversion relation between the deformation quantity and the relative conveying quantity is modeled, so that the conveying quantity of the belt conveyor is measured through video monitoring, the time is saved, the efficiency is improved, and the measurement is accurate.
Description
technical field [0001] The invention relates to a method for measuring material delivery volume, in particular to a method for measuring instantaneous relative delivery volume of a belt conveyor based on video analysis. Background technique [0002] Conveyor belts, belt conveyors are widely used in agriculture, industrial and mining enterprises, and transportation industries to transport various solid block and powder materials or finished items. The conveyor belt can be transported continuously, efficiently, and at a large angle. The operation is safe, the conveyor belt is easy to use, the maintenance is easy, the freight is low, and the transportation distance can be shortened, the project cost can be reduced, and manpower and material resources can be saved. [0003] However, at present, for the transportation of materials on the conveyor belt, the weight measurement is generally carried out before or after the transportation, and it is difficult to directly measure the w...
