Embodiment Construction

[0027] The structure of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0028] like figure 1 As shown, the volumetric mass calculation method of 3D imaging modeling mainly includes stockpile cutting into square columns, data returning to columns, intra-column data processing, stockpile data compensation, inter-column data processing, etc.

[0029] The background object data processed by the present invention is stockpile height data with azimuth information, and through the processing methods such as data returning to the column, data processing in the column, edge compensation of the stockpile, inter-column mean value filtering and other processing methods, a complete three-dimensional model of the stockpile is finally obtained , and calculate the volume and mass of the stockpile.

[0030] 1) The maximum size range of the background stockpile is: length (X axis) 220 meters, width (Y axis) 50 meters,...

Abstract

The invention provides a computational method for modeling the volume of a material pile. In the method, a plurality of square columns are formed by longitudinal and transverse two-dimensional cutting of sampled data of the original profile of the material pile, column surface height data of each square column is obtain by filtering processing, the volume of each square column is computed, and the volumes of the square columns are added to obtain the total volume of the whole material pile. The method can be applied in the field of material pile volume measurement effectively, so that material pile profile sampled data obtained by the vertical scanning of the material pile by a measurement system is processed to obtain a continuous surface three-dimensional model of the material pile, and the volume of the material pile is computed at the same time. The processing process of the method comprises: cutting the material pile into square columns; distributing data into columns; processing data in columns; compensating for material pile data; processing data among columns; and the like. The three-dimensional model of the material pile can be displayed in several modes such as an original data mode, an after-modeling color mode, isohypse line color-based mode and the like. The method is applied in enterprises and public institutions such as power plants, coal plants and the like for realizing the accurate measurement and computation and visual display and management of the volume of the material pile.

Description

technical field [0001] The invention relates to the field of stockpile measurement, in particular to a three-dimensional imaging of a stockpile and a volume calculation method thereof. Background technique [0002] At present, in factories and mines with stockpiles of coal, ore, etc., important production data such as the volume and weight of stockpiles have been estimated by traditional manual methods. Affected by bad weather and errors introduced by manual measurement, estimation The results are often not ideal. Contents of the invention [0003] The object of the present invention is to provide a method for modeling and calculating the volume of a stockpile. This method obtains a complete three-dimensional model of the stockpile by performing cutting, filtering, and edge compensation on the sampling data of the stockpile surface obtained by scanning the stockpile. Based on this, the volume and mass of the stockpile are calculated. [0004] In order to achieve the abov...
