Abstract
We present a new method which provides object location priors for previously unseen object 6D pose estimation. Existing approaches build upon a template matching strategy and convolve a set of reference images with the query. Unfortunately, their performance is affected by the object scale mismatches between the references and the query. To address this issue, we present a finer-grained correlation estimation module, which handles the object scale mismatches by computing correlations with adjustable receptive fields. We also propose to decouple the correlations into scale-robust and scale-aware representations to estimate the object location and size, respectively. Our method achieves state-of-the-art unseen object localization and 6D pose estimation results on LINEMOD and GenMOP. We further construct a challenging synthetic dataset, where the results highlight the better robustness of our method to varying backgrounds, illuminations, and object sizes, as well as to the reference-query domain gap.
