Problems solved by technology
This method can only rely on historical data for repeated inspection work. When performing new inspection tasks, it is necessary to manually operate the UAV inspection platform in advance to obtain track data, hovering GPS information, and camera rotation data information. repetitive work
Moreover, the outdoor working environment of drones is complex, and the drone platform cannot guarantee the accuracy of repeated inspection routes and GPS information, resulting in inaccurate information collection

The invention discloses an intelligent inspection method and system based on the three-dimensional information of the transmission line, which acquires the three-dimensional data of the target object, extracts the model, position information and / or information of the accessory parts of the target object of the transmission line; The three-dimensional model of the target object or / and the attached parts; according to the type information of each target object, obtain its local coordinate information in three-dimensional space, and calculate the three-dimensional space position of the center of each target object; The three-dimensional space position of the component, determine the hovering coordinates, formulate the inspection path and / or local flight strategy according to the direction of the transmission line and the hovering coordinates, and generate the flight inspection task.
Description
technical field [0001] The invention relates to an intelligent inspection method and system based on three-dimensional information of transmission lines. Background technique [0002] With the development of society and economy, the demand and dependence on electricity are increasing day by day, and the operation status of transmission lines directly affects the stability of society and the development of national economy. As a new and efficient inspection mode, UAV inspection technology is introduced into daily inspection tasks, which greatly improves the work efficiency and accuracy of inspection. However, at present, the inspection task of the UAV on the transmission line is still mainly completed by manual operation. The staff realizes the manual control of the UAV inspection platform through the ground station and the remote control. 1. The requirements for inspection experience are relatively high, and an intelligent and automated inspection system is urgently needed ...
