Embodiment Construction

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041]First of all, it needs to be explained that tailings ponds are usually built on the basis of making full use of the original terrain, by intercepting and building dams step by step to form a certain storage capacity, and stacking tailings or solid waste in it, with obvious step-by-step Stacking features. Therefore, if high-resolution remote sensing data is used to...

Abstract

The invention discloses a tailings pond scale information extracting method and device. The scale of a tailings pond can be quickly and efficiently calculated at low cost. The method comprises the steps that the high-resolution remote sensing data of the tailings pond and original terrain data before the construction of the tailings pond are acquired, wherein the scale information of the tailings pond is to be extracted; the high-resolution remote sensing data and the original terrain data are registered; based on the high-resolution remote sensing data, remote sensing recognition is carried out on plane features related to the scale of the tailings pond to acquire plane features related to the tailings pond; the original terrain data are used to carry out terrain profile and other topographic analysis on the plane features related to the tailings pond to acquire the vertical elevation information of a key edge point of the tailings pond; the vertical elevation information of the key edge point is used to reconstruct a three-dimensional spatial structure after the construction of the tailings pond; and based on the reconstructed three-dimensional spatial structure and according to the graded three-dimensional structure of each level of dam body of the tailings pond, the total area, the total dam height and the total capacity of the tailings pond are calculated.

Description

technical field [0001] The invention relates to the field of remote sensing data processing and information extraction, in particular to a tailings pool scale information extraction method and device. Background technique [0002] The size of the tailings pond is an important parameter information of the tailings pond, and an important factor that determines the environmental safety around the tailings pond. It has become the regulatory standard for the classification and classification of tailings ponds in the fields of safety supervision and environmental protection (usually the larger the scale, the corresponding supervision standard) The higher the value, the stricter the supervision) is an important basis for judging the supervision work. Therefore, it is very critical to accurately grasp the important information of tailings pond size. However, the current supervision departments in the fields of safety supervision and environmental protection mainly obtain the inform...
