[0002] A wind engine is a device that converts the kinetic energy of the airflow into mechanical energy. This device is usually connected and drives a generator to generate electricity. Among them, the quality and design of the blades directly affect the efficiency of wind energy conversion and are important factors that control the utilization of wind energy. Blades During the use process, it will be damaged and cracked due to the influence of bad weather and service life, which will affect the rotation of the blade and even cause the blade to break. Therefore, it is particularly important to conduct non-destructive testing on the blade regularly. The current blade detection can be through ultrasonic, Acoustic emission combined with infrared thermal imaging and other methods, but due to the low accuracy of some remote detection data, when it is necessary to directly fit the blades for detection, due to the high installation position of the blades and the large volume of the blades, the detection is inconvenient
