Research on Three-dimensional Reconstruction Model of Power Line Based on Point Cloud Data

According to the force characteristics of power line, combined with the research and analysis of the model, a new three-dimensional reconstruction model of power line is proposed. The model is composed of two projection models of the power line in the plane where the horizontal specific load is located and the plane in which the vertical specific load is located. Unlike existing models: First of all, the two projection models that make up the reconstructed model have the highest degree of equality. Secondly, the least square method based on orthogonal polynomial is used as the fitting method of projection model. Finally, the fitting times of power line reconstruction model are determined by experimental analysis.
