Embodiment Construction

[0025] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes the following steps: (1), according to the image captured by the camera, obtain the image collected by the front end; (2), according to the obtained image, set the reference stockpiling state; (3), analyze the reference stockpiling state image, Estimate its reference volume; (4) After reaching the set time, estimate the stacking volume again; (5) Use the volume value obtained twice to calculate the volume change rate. In step (2), the video image at a certain moment is selected, and the stockpiling state at this moment is taken as the reference state for measuring the volume change rate, and the stockpiling volume in the benchmark state is taken as the initial volume, and the stockpiling volume is detected on this basis The change. In step (3), the steps of estimating the stacking reference volume are: extracting image features, identifying the stacking area in the ...

Abstract

The invention belongs to the technical field of video monitoring, video image processing and analysis technology and machine vision, and particularly relates to a method for estimating the volume change rate of stacked materials based on image features. The method for estimating the volume change rate of stacked materials based on image features is characterized by including the steps of: (1) obtaining an image collected at a front end according to the image shot by a camera; (2) setting a reference stacked material state according to the acquired image; (3) analyzing a reference stacked material state image, and estimating the reference volume; (4) after reaching a set time, estimating the volume of the stacked materials again; and (5) utilizing volume values obtained by two times to calculate the volume change rate. The method has the beneficial effects that intelligent supervision of stacked materials in industry is realized, input cost is greatly reduced, the volume change rate of the stacked materials can be automatically detected in real time, manual measurement and detection are not needed, and processes of installation and maintenance of measuring equipment and complex operation are avoided.

Description

(1) Technical field [0001] The invention belongs to the field of video monitoring, video image processing and analysis technology and machine vision technology, and in particular relates to a method for estimating the volume change rate of stockpiles based on image features. (2) Background technology [0002] In recent years, there have been many thefts of coal, steel, and waste resources used for incineration, which have made enterprises have an increasing demand for safety precautions in industrial stacking management. The safety management of stacking materials in industry is a major problem facing enterprises today, especially the safety management of bulk raw materials in industries such as iron and steel, coal mines, electric power, metallurgy, and nonferrous metals is an important part of production management. The traditional method of manual monitoring can no longer meet the demand. The real-time and efficient detection of the volume change of the raw materials in t...
