Method and device for converting ultrasonic image into 3D model

The invention discloses a method and a device for converting an ultrasonic image into a 3D model, relates to the technical field of image processing, is more visual, and facilitates doctor-patient communication. The accuracy of a detection result is greatly improved; and meanwhile, medical anatomy, learning and the like are facilitated. The method comprises the steps of obtaining multiple to-be-converted ultrasonic images; extracting a feature map of each to-be-converted ultrasonic image to obtain a feature map map; according to the coordinate of each point on the feature map, obtaining the category of each point on the feature map and a target detection frame; extracting each point in the foreground class on the feature map to form a to-be-detected image with the target detection frame; adopting a threshold segmentation method to obtain an automatic segmentation image; and obtaining a 3D conversion model according to the automatic segmentation image. The method is mainly used for medical clinical diagnosis.
