METHOD AND APPARATUS FOR GENERATING REFERENCE DATA

Document Type and Number:

WIPO Patent Application WO/2021/227995

Kind Code:

A1

Abstract:

A method and apparatus for generating reference data, relating to the field of image processing. The method comprises: obtaining a sample image, wherein the sample image comprises a target object (101); obtaining coordinate values of annotation points annotating the target object in the sample image, wherein an image of the target object is comprised in a polygon image taking the annotation points as vertices (102); and generating reference data corresponding to the sample image on the basis of the coordinate values of the annotation points in the sample image (103). According to the method, the coordinate values corresponding to the annotation points used for annotating the target object in the sample image are obtained, and the reference data corresponding to the sample image is automatically generated on the basis of the coordinate values corresponding to the annotation points, thereby simplifying the operation of obtaining the reference data, and improving the efficiency of obtaining the reference data.
