A 3D real scene reconstruction system of a coal storage yard and a method for quickly estimating the amount of coal

Abstract

The invention discloses a coal storage yard three-dimensional live-action reconstruction system and a coal quantity fast estimation method, and belongs to the technical field of the computer vision. Areconstruction system comprises a high-definition camera, an industrial-level four-rotor unmanned aerial vehicle, an unmanned aerial vehicle ground station and a data server; the high-definition camera, the industrial-level four-rotor unmanned aerial vehicle and the unmanned aerial vehicle ground station form a data collection part of the system; the industrial-level four-rotor unmanned aerial vehicle is used for loading the high-definition camera to acquire an orthographic image of a coal storage yard; the unmanned aerial vehicle ground station controls the unmanned aerial vehicle to fly according to a polling path in the coal storage yard; the data server receives the orthographic image acquired by the high-definition camera through a wireless network, performs coal storage yard three-dimensional virtual reconstruction and estimates the coal quantity. The system disclosed by the invention has the advantages that the system is suitable for the coal quantity estimation of the large-scale outdoor coal storage yard, and can be applied to the storage yard storage and transportation management of other industries; the coal quantity at the coal mine port, the coal transport port and the thermal power plant and like coal storage yards for producing or using the coal can be accurately checked.

Description

technical field [0001] The invention relates to a method for rapidly estimating coal quantity in a coal storage yard in the technical field of computer vision, in particular to a three-dimensional real scene reconstruction system for a coal storage yard and a method for rapidly estimating coal quantity. Background technique [0002] For enterprises that produce or use coal such as coal mines, coal transportation ports, and thermal power plants, accurate accounting of the amount of coal in coal storage yards is crucial to the business decision-making and production plan formulation of the above-mentioned enterprises, and directly affects the economic benefits of the enterprise. [0003] At present, laser measurement or photogrammetry is usually used to replace manual estimation methods to realize the estimation of coal storage yard coal volume and improve the real-time and accuracy of storage and transportation management. Among them, laser measurement is mainly based on the ...
