How does GigaPose's approach compare to other state-of-the-art methods in terms of accuracy and speed

GigaPose's approach stands out in terms of both accuracy and speed compared to other state-of-the-art methods. In terms of accuracy, GigaPose demonstrates a significant improvement over existing methods, as shown by its higher average precision on the BOP benchmark [58]. The method achieves state-of-the-art accuracy in CAD-based novel object pose estimation, showcasing robustness to segmentation errors and providing more accurate pose estimates. Additionally, GigaPose can seamlessly integrate with existing refinement methods for further enhancement.
When it comes to speed, GigaPose excels by being significantly faster than other methods like MegaPose [28]. For coarse object pose estimation per detection, GigaPose offers a remarkable speedup factor of 35× compared to MegaPose. This is achieved through efficient template sampling in a two-degrees-of-freedom space and fast nearest-neighbor search in feature space. The reduced processing time makes GigaPose highly suitable for real-time applications where quick and accurate object pose estimation is crucial.
