Electric transmission line corridor geological disaster survey method and system

Abstract

The present invention belongs to the technical field of geological disaster survey, and discloses an electric transmission line corridor geological disaster survey method and system. The method comprises the steps of: constructing a three-dimensional scene model graph of an electric transmission line corridor through aerial photo and location of an unmanned aerial vehicle, and collecting meteorological information and electric transmission line operation information in real time; performing classification of the three-dimensional scene model graph of the electric transmission line corridor based on a supervised classification method to identify a terrain type and a disaster generation region; taking electric transmission line poles and towers as main research subjects to perform distinguishing of change states of the poles and towers; and finally, taking the collected meteorological information, the electric transmission line operation information, suspected disaster region informationand the change information of the poles and the towers as data input to compare with a current geological disaster model library so as to perform early warning for regions where disasters are likelyto happen. The electric transmission line corridor geological disaster survey method and system can achieve object-level monitoring of the poles and the towers so as to improve the whole geological disaster survey quality and efficiency and guarantee the accurate assessment of the geological disasters.

Description

technical field [0001] The invention relates to the technical field of geological disaster survey, in particular to a method and system for geological disaster survey of transmission line corridors. Background technique [0002] 70% of my country is mountainous, most of which are located in the Midwest. With the needs of social and economic development, a large number of underground mineral resources are mined, resulting in a large number of mine geological disasters. The power system is a special and organic part of lifeline engineering, and natural disasters with strong suddenness and destructiveness are becoming an important threat to the instability of the power system. Especially in Guizhou Province, due to numerous mountainous hills, complex topography, more transmission lines than in the wild, many points, long lines, and wide areas, it is vulnerable to natural disasters such as landslides, and its safe and reliable operation is seriously threatened. [0003] There ...
