Multi-dimensional feature fusion and dimension reduction method for transmission line data used for unmanned aerial vehicle maintenance route map setting and storage medium

Abstract

The application provides a power transmission line data-oriented multi-dimensional feature fusion and dimension reduction method and a storage medium, relates to data processing technology, and performs standardization processing on the multi-dimensional influence data to obtain standard data; determines that the feature structure is a two-dimensional feature, takes the standard data as first data, counts first frequencies of each sub-item category in the first data, performs nonlinear weighted fusion processing on the first frequencies to obtain a first fusion value; when the feature type is a multi-dimensional feature, takes the standard data as second data, performs hierarchical processing on the second data based on a preset condition logic and counts second frequencies of each risk level, performs nonlinear weighted fusion processing according to the risk level and the second frequency to obtain a second fusion value; obtains a risk value of a monitoring target according to the first fusion value and the second fusion value, determines an abnormal target based on the risk value, and determines a maintenance route map of a UAV according to a target area of the abnormal target.
