Method and device for constructing 3D model based on 2D ultrasound image cognition

Abstract

Embodiments of the present invention provide a method and device for constructing a three-dimensional model based on two-dimensional ultrasound image cognition. The method includes: collecting two-dimensional ultrasound images of a target object through several slices; acquiring key anatomy included in the ultrasound two-dimensional images Point cloud data of structural points; through the identification and labeling of anatomical structure points, point cloud data containing anatomical structure point position, posture, section information, and anatomical structure information are obtained. Relying on the knowledge base about the structure of the target object and point cloud data, the position and posture of the points of the anatomical structure can be recognized. A point cloud in three-dimensional space is formed, and an initial three-dimensional model of the target object is constructed. And through the matching and fitting of multiple 2D slices and 3D initial model interactive cuts, an accurate 3D model is obtained. By applying the embodiments of the present invention, a three-dimensional model can be constructed.

AI Technical Summary

Problems solved by technology

For objects with unpredictable shape changes, the consistency between the actual shape of the object and the set model is reduced

Especially when the "target" exceeds the coverage of the ultrasonic "fan" and the edges of the image are blurred or missing, the shape of the organ in the test result may actually be very different from the shape of the real organ

[0005] Therefore, the prior art has the technical problem of poor accuracy of the constructed 3D model
