Abstract

The invention relates to a fan blade inspection method, a fan blade inspection device, an unmanned aerial vehicle and a storage medium. The fan blade inspection method comprises the steps of: acquiring a first image of a draught fan above the draught fan; analyzing the first image, and determining the orientation of the draught fan; planning an inspection path according to the orientation, an inverted Y shape and lengths of fan blades and position information of the center of a hub of the draught fan; and carrying out image acquisition on the fan blades according to the inspection path so as to carry out defect analysis on the fan blades through using the acquired image. Since the inspection process of the fan blades relates to key steps, namely, image acquisition of the fan blades is completed through autonomously determining the orientation of the draught fan and planning the inspection path by means of the unmanned aerial vehicle, the whole process does not need participation of inspection personnel and is autonomously completed by means of the unmanned aerial vehicle, the safety of the inspection personnel is effectively guaranteed, and meanwhile the inspection efficiency of the fan blades is greatly improved.

Description

technical field [0001] The present application relates to the field of new energy, in particular to a method and device for inspection of fan blades, a drone and a storage medium. Background technique [0002] Fan blades are an important component of wind turbines. Due to the harsh environment of wind turbines, fan blades are easily damaged by wind, sand, rain, snow, lightning and other natural factors when operating in harsh environments. Defects such as shedding, trachoma, lightning strikes, blade wear, etc. Therefore, regular inspections of fan blades are required. [0003] In the traditional technology, manual means are usually used to realize the patrol inspection of the fan blades. However, the timeliness of the traditional method is low, and the safety of the inspectors cannot be guaranteed. Contents of the invention [0004] Based on this, it is necessary to provide a method, device, unmanned aerial vehicle, and storage medium for the inspection of fan blades, ai...
