- Abstract summary: We present an end-to-end deep phase correlation network (DPCN) to match heterogeneous sensor measurements.
The primary component is a differentiable correlation-based estimator that back-propagates the pose error to learnable feature extractors.
With the interpretable modeling, the network is light-weighted and promising for better generalization.

- Abstract: The crucial step for localization is to match the current observation to the
map. When the two sensor modalities are significantly different, matching
becomes challenging. In this paper, we present an end-to-end deep phase
correlation network (DPCN) to match heterogeneous sensor measurements. In DPCN,
the primary component is a differentiable correlation-based estimator that
back-propagates the pose error to learnable feature extractors, which addresses
the problem that there are no direct common features for supervision. Also, it
eliminates the exhaustive evaluation in some previous methods, improving
efficiency. With the interpretable modeling, the network is light-weighted and
promising for better generalization. We evaluate the system on both the
simulation data and Aero-Ground Dataset which consists of heterogeneous sensor
images and aerial images acquired by satellites or aerial robots. The results
show that our method is able to match the heterogeneous sensor measurements,
outperforming the comparative traditional phase correlation and other
learning-based methods. Code is available at

In this paper, we argue that one effective alternative is to devise an approximate loss who can achieve trend-level alignment with SkewIoU loss.
Specifically, we model the objects as Gaussian distribution and adopt Kalman filter to inherently mimic the mechanism of SkewIoU.
The resulting new loss called KFIoU is easier to implement and works better compared with exact SkewIoU.
