Description

technical field

[0001] The invention belongs to the technical field of automatic inspection by unmanned aerial vehicles, in particular to an automatic flight method for inspection of blade area routes of wind turbine blades. Background technique

[0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. Wind turbines are generally composed of a cabin (transmission mechanism and generator), blades, towers and other components. During the operation of wind turbines, the surface of the blades will show various damages, such as paint peeling, blade freezing, cracking, lightning strikes, etc. At present, the traditional wind turbine blade inspection usually uses manual climbing on the wind turbine and high-altitude operations for inspection, which not only consumes a lot of manpower, but also has great potential safety hazards.

[0003] Therefore, the detection of wind turb...
