Transformer substation wire live-line distance verification method and device based on laser point cloud technology

The invention discloses a transformer substation wire live-line distance verification method and device based on a laser point cloud technology. The method comprises the steps that a three-dimensional model is established according to design parameters and position information of a to-be-verified line; acquiring point cloud data corresponding to the to-be-verified line according to the position information; and matching the point cloud data with the three-dimensional model, and verifying the point cloud data according to the design parameters to obtain a verification result. A three-dimensional model is established through design parameters and position information of a to-be-verified line, point cloud data corresponding to the to-be-verified line is collected according to the position information to generate a point cloud model, then the three-dimensional model is matched with the point cloud model, and a live wire is automatically identified through the design parameters in the three-dimensional model.
