In this paper we present a novel generalizable object pose estimation method to determine the object pose using only one RGB image. Unlike traditional approaches that rely on instance-level object pose estimation and necessitate extensive training data our method offers generalization to unseen objects without extensive training operates with a single reference image of the object and eliminates the need for 3D object models or multiple views of the object. These characteristics are achieved by utilizing a diffusion model to generate novel-view images and conducting a two-sided matching on these generated images. Quantitative experiments demonstrate the superiority of our method over existing pose estimation techniques across both synthetic and real-world datasets. Remarkably our approach maintains strong performance even in scenarios with significant viewpoint changes highlighting its robustness and versatility in challenging conditions.
