Claim 0:
1. An object pose obtaining method, comprising:
extracting an image block of an object from an image, and generating a local coordinate system corresponding to the image block;
obtaining 2D projection key points in an image coordinate system corresponding to a plurality of 3D key points on a 3D model of the object;
converting the 2D projection key points into the local coordinate system to generate corresponding 2D prediction key points;
obtaining direction vectors between each pixel point in the image block and each 2D prediction key point, and obtaining a 2D target key point corresponding to each 2D prediction key point based on the direction vectors; and
determining a pose of the object according to the 3D key points and the 2D target key points.
