Abstract

The invention discloses a power transmission line external damage prevention identification method and terminal, and the method comprises the steps: establishing an external damage sample library of apower transmission line, and formulating an evaluation standard; establishing an external damage detector; training the external damage detector to converge by using a coco data set to obtain a pre-training model; migrating the pre-training model to the external damage sample library for training to obtain a training model; evaluating the training model according to the evaluation standard to obtain an optimal model; and identifying a to-be-identified image by using the optimal model. According to the method, the external damage target on the power transmission line can be rapidly identified,the identification precision is high, and the reliability is good.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method and terminal for anti-breakage recognition of transmission lines. Background technique [0002] In recent years, with the rapid development of the economy, the construction of urban and rural infrastructure has increased, resulting in sudden and seasonal external force damage to overhead transmission lines caused by illegal tree planting, house building, and construction operations. 1. The mobility of the machinery is strong, the randomness is large, and it is difficult to prevent it. The invasion and damage of foreign objects has become one of the biggest threats and hidden dangers to the safe and stable operation of overhead transmission lines. [0003] Currently, target detection methods mainly focus on video surveillance and video image processing. For example: [0004] 1. Divide the target detection into two stages, that is, first use deep CNN to disting...
