Method of generating model, system for generating model, device, storage medium, and program product

A generation method of a model, comprising:

• acquiring a plurality of ultrasound images of a target object and corresponding probing position information;
• extracting a contour feature point set of the target object in each of the ultrasound images, the contour feature point set comprising a plurality of contour feature points;
• obtaining spatial position information of each of the contour feature points based on the contour feature point set corresponding to each of the ultrasound images and the probing position information;
• obtaining a target projection point of each of the contour feature points on a standard three-dimensional model corresponding to the target object according to the spatial position information of each of the contour feature points;
• and
• calibrating the standard three-dimensional model based on the spatial position information of each of the contour feature points and the target projection point, to obtain a target three-dimensional model of the target object;
• wherein the step of obtaining the target projection point of each of the contour feature points on the standard three-dimensional model corresponding to the target object according to the spatial position information of each of the contour feature points comprises:
• acquiring an intersection point set of the contour feature point set corresponding to each of the ultrasound images with the standard three-dimensional model;
• aligning the contour feature point set with the corresponding intersection point set using a preset alignment method based on the spatial position information;
• and
• mapping each of the contour feature points in the aligned contour feature point set onto the standard three-dimensional model, to obtain the target projection point corresponding to each of the contour feature points.
