Title:
MONITORING METHOD AND APPARATUS, AND COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/116114
Kind Code:
A1
Abstract:
A monitoring method and apparatus, and a computer storage medium. The monitoring method comprises: acquiring a target medical image obtained by imaging a target object at a target angle (101); acquiring a reference image corresponding to the target object at the target angle (102); according to the reference image and the target medical image, determining a first offset of the target object in a first direction and a second offset thereof in a second direction (103); and according to a scaling ratio of the target object in the reference image and a scaling ratio of the target object in the target medical image, determining a third offset of the target object in a third direction that is perpendicular to the first direction and the second direction (104). A three-dimensional offset can be obtained simply by performing single-angle imaging at one moment, and multi-angle photographing does not need to be performed at different moments, such that the real-time performance is better, and the accuracy is higher due to the absence of a time interval.
