Research on transmission conductor extraction method based on mainline projection LSD algorithm

Reliable extraction of transmission lines is crucial for line feature identification, fault diagnosis and condition evaluation. The existing image extraction methods still have deficiencies such as inaccurate wire extraction, high arithmetic power consumption, and inability to complete operations at the edge side. This paper proposes a transmission conductor extraction method based on the main line projection LSD algorithm. First, the conductor is segmented from the background by the LSD algorithm, a processing matching algorithm for the main line projection is proposed for the errors in the results, and a conductor parameter estimation method is established based on the extraction results. The method requires low arithmetic power of the equipment and can be deployed at the side end to achieve conductor extraction and provide a basis for further data analysis.
