Gesture control method, system and device and storage medium

The invention provides a gesture control method, system and device and a storage medium, and the method comprises the steps: receiving image data sent by an image collection device, inputting to-be-recognized images in the image data into a trained gesture detection model frame by frame, and obtaining a gesture detection result of each frame of to-be-recognized image; when it is detected that a target human body object appears in the gesture detection result, determining a target gesture area bounding box where the target gesture object is located from the target gesture detection result according to human body feature data of the target human body object; determining a target control instruction having a mapping relation with a target gesture action from a mapping relation library of the gesture action and the control instruction according to the target gesture action displayed by the target gesture object in the target gesture area bounding box; and sending the target control instruction to a screen display
