[0002] Image recognition refers to the technology of using computers to process, analyze and understand images to identify targets and objects of various different patterns. It is a practical application of deep learning algorithms. At present, image recognition technology is generally used for face recognition, commodity recognition and object recognition.

[0003] For example, an image acquisition device is placed on a drone, and the drone is used to scan and photograph objects to obtain image information. The acquired images are subjected to preprocessing, feature extraction, and image recognition steps to analyze and judge the image information.

[0004] At present, image acquisition equipment carried by drones is usually installed on the lower surface of the drone or on the nose of the drone. In this way, the image acquisition equipment usually changes the position and angle of the captured image according to the movement and rotation of the drone. This requires precise control of the drone and consumes more energy. The acquisition angle of the image acquisition equipment needs to be adjusted for multiple times before a better acquisition effect can be achieved. Utility Model Content
