Abstract
The present application provides a method and an apparatus for three-dimensional object pose estimation, a device and a storage medium. The method includes: calculating a graph of a previous frame and a graph of a current frame for a target three-dimensional object; performing a matching calculation on the graph of the previous frame and the graph of the current frame using a graph matching algorithm to obtain a vertex correspondence relationship between the graph of the previous frame and the graph of the current frame; calculating a pose of the target three-dimensional object in the current frame according to the vertex correspondence relationship, a pose of the target three-dimensional object in the previous frame and a PnP algorithm. The matching accuracy of feature points is effectively improved, and thereby the accuracy of three-dimensional object pose estimation is improved.
