Claim 8:
9. The method of claim 7, wherein the step of obtaining the third sample two-dimensional coordinates of each key point of the sample to-be-imitated object in the pre-labeled second sample two-dimensional image, and the predetermined first sample three-dimensional coordinates corresponding to the third sample two-dimensional coordinates, comprises:
collecting, by cameras hanging around the sample to-be-imitated object, a two-dimensional image of the sample to-be-imitated object;
obtaining three-dimensional coordinates of each key point of the sample to-be-imitated object in a world coordinate system using a multi-view fusion algorithm according to the collected two-dimensional image; and
determining, the first sample three-dimensional coordinates in a camera coordinate system corresponding to the three-dimensional coordinates of each key point of the sample to-be-imitated object in the world coordinate system, and the third sample two-dimensional coordinates in an image coordinate system of the pre-labeled second sample two-dimensional image corresponding to the first sample three-dimensional coordinates, based on parameters and pose of each of the cameras, and wherein the parameters comprise a focal length of each camera.
