Tailings pond scale information extracting method and device

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...
