Augmented reality-based ultrasonic scanning guiding method and system

The invention provides an augmented reality-based ultrasonic scanning guiding method and system. The method comprises the steps: carrying out the real-time photographing and displaying a real scene image of a real scanning scene through augmented reality equipment, respectively tracking a background positioning identifier and a probe positioning identifier according to the real scene image to obtain first pose information of the background positioning identifier and second pose information of an ultrasonic probe; by the augmented reality equipment, superposing and rendering a scanning target region on the real scene image according to the first pose information and pre-acquired spatial position calibration information of the scanning target region of a subject, and superposing and rendering a probe position region on the real scene image according to the second pose information; and by the augmented reality equipment, generating and displaying a corresponding scanning prompt according to a coincidence state b
