Power transmission tower type determining method based on aerial image analysis

Using helicopter aerial inspection of power transmission line is an effective measure in complicated geographical environment. At the present time, the inspection of the aerial image rely on manual observation, its efficiency is low and undetected always happen by mistake or careless. An automatic analysis method by computer has been proposed to process aerial video. After pretreatment, the image quality has improved. Edge detection is utilized to determine the target area of the image, and tower contours is obtained by curve fitting. Based on variety tower features, template matching method is used to identify the power transmission tower type. The analysis results of the aerial image showed that the identification method is feasible. It can greatly reduce the labor burden of inspection, and improve the efficiency of aerial image analyzing.
