Embodiment Construction

[0029] A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0030] Such as figure 1 As shown, a method for monitoring the dynamic change of the amount of slag in the slag pile body provided by the embodiment of the present invention includes the following steps:

[0031] S1. Obtain the original image data of the slag body through the remote sensing of the UAV;

[0032] S2. According to the current water and soil conservation monitoring technical regulations, process the original image data of the slag body to form a three-dimensional coverage image of the slag body;

[0033] S3. Extract DEM (Digital Elevation Model) data from the three-dimensional overlay image of the slag body to form a DEM (Digital Elevation Model) result, and after orthorectification of the DEM (Digital Elevati...

Abstract

The invention relates to the technical field of production and construction project water and soil conservation monitoring, and discloses a slag body slag volume dynamic change monitoring method. Themethod comprises the following steps that S1, original image data of the slag body slag volume is obtained through drone remote sensing; S2, according to existing water and soil conservation monitoring technical regulations, the original image data is processed, and a three-dimensional cover image is formed; S3, DEM data is extracted from the three-dimensional cover image, a DEM result is formed,orthorectification is conducted on the DEM result, and a DOM result is obtained; S4, according to the DOM result, a detailed location is identified, and the slag volume is calculated; S5, according tothe DEM data, a three-dimensional model of a slag body is built, and the slag volume is calculated; S6, the dynamic variation of the slag body is obtained; S7, the dynamic variation of the slag volume is obtained. The slag body slag volume dynamic change monitoring method is simple and practical, and quantitative, fine and information development of water and soil conservation monitoring work ispromoted.

Description

technical field [0001] The invention relates to the technical field of water and soil conservation monitoring for production and construction projects, in particular to a method for monitoring dynamic changes in the amount of slag in a slag pile. Background technique [0002] Using UAV low-altitude aircraft as a remote sensing platform, UAV remote sensing provides a new technical support for soil and water conservation monitoring in production and construction projects, but the application of this technology in soil and water conservation monitoring in production and construction projects is still in its infancy. Unified and effective methods and standards have not been formed. [0003] The present invention combines the UAV remote sensing technology with the current normative procedures for soil and water conservation monitoring, and constructs a UAV-based remote sensing system from three aspects: basic data acquisition, monitoring information extraction, and information ap...
