Abstract

The invention provides a three-dimensional modeling system and a three-dimensional modeling method of a power transmission line pole. The system comprises the components of a three-dimensional modeling module which is arranged in a ground station, a multi-rotor unmanned aerial vehicle, a differential GPS unit which is arranged in the multi-rotor unmanned aerial vehicle, and a sensing control assembly which is arranged at the center of bottom of the multi-rotor unmanned aerial vehicle. The method is characterized in that through making the multi-rotor unmanned aerial vehicle fly around the power transmission line pole in uniform speed, data of the multi-rotor unmanned aerial vehicle are acquired in real time; and three-dimensional modeling is performed on the power transmission line pole according to the data. The system and the method according to the invention can effectively coordinate each functional module of the unmanned aerial vehicle, thereby ensuring stable flight of the unmanned aerial vehicle. The data which are acquired through flight control and differential GPS of the unmanned aerial vehicle are sufficiently used. A two-dimensional image which is aerially photographed by the unmanned aerial vehicle is fused with geographical gesture information. The three-dimensional modeling system and the three-dimensional modeling method have advantages of realizing low cost and high modeling precision, preventing personal injury of maintenance personnel, and supplying accurate data for researching of the power transmission line pole.

Description

technical field [0001] The invention relates to the technical field of transmission line tower modeling, in particular to a three-dimensional modeling system and method for transmission line towers. Background technique [0002] The multi-rotor UAV inspection system has the advantages of convenience, flexibility, speed and convenience, and can achieve efficient and low-cost acquisition of aerial images of transmission line towers. However, thousands of two-dimensional images are obtained for each transmission line tower inspection. Professional maintenance personnel are required to screen and identify one by one, which is inefficient and error-prone. [0003] In the past, the sequence images captured by drones only contained two-dimensional information, and could not reproduce the three-dimensional geometric structure of entities. The traditional 3D reconstruction method is expensive and inefficient. Although the manned helicopter-borne lidar measurement system can provide ...
