Embodiment 1

[0052] Such as figure 1 As shown, Embodiment 1 of the present invention provides an intelligent route planning method for refined inspection of transmission lines, which uses unmanned aerial vehicles to collect 3D point cloud data of target transmission lines, and then uses the 3D point cloud data as a basis to perform three-dimensional The point cloud data is processed to finally generate a route that meets the requirements (that is, the 3D point cloud data model is processed to obtain waypoints, the waypoints are connected in series to calculate and plan the route, and finally a route that meets the requirements is generated), including the following steps:

[0053] Step S100: first obtain all 3D point cloud data on the channel based on the target transmission line (wherein the collection of the above-mentioned 3D point cloud data can be carried out by drones or helicopters equipped with laser radar scanners to collect and obtain the target transmission line, for the above sp...

Abstract

The invention discloses an intelligent route planning method for refined inspection of a power transmission line. The method comprises the steps: carrying out collection of three-dimensional point cloud data of a target power transmission line through an unmanned aerial vehicle, and then carrying out the processing on the three-dimensional point cloud data based on the three-dimensional point cloud data, and finally generating a route meeting the requirements; and processing a three-dimensional point cloud data model to obtain waypoints meeting requirements and generating a route by considering reference factors such as a safety distance between a waypoint and a photographing point, a tower crossing height, a height layering area and a middle-phase area range. The intelligent route planning method has the function of obstacle avoidance refined route planning, and the inspection efficiency and the inspection quality of the power transmission line are guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric power inspection, in particular to an intelligent route planning method for refined inspection of power transmission lines. Background technique [0002] At present, transmission lines are large in scale, wide in coverage, and pass through complex terrain environments. Regular fine-grained inspections are not only labor-intensive and time-sensitive, but also difficult to observe the line body in an all-round way. [0003] With the development of lidar technology, the operation of UAV lidar system has gradually become a new means of power line inspection. After research and development, our company has designed and developed various types of airborne lidar systems; the airborne lidar system is based on the UAV platform and uses the lidar scanning system to collect high-precision point cloud data in real time, dynamically, and in large quantities. image information. However, in the specific inspe...
