Query: DRO: Deep Recurrent Optimizer for Structure-from-Motion   There are increasing interests of studying the structure-from-motion (SfM)
problem with machine learning techniques. While earlier methods directly learn
a mapping from images to depth maps and camera poses, more recent works enforce
multi-view geometry constraints through optimization embedded in the learning
framework. This paper presents a novel optimization method based on recurrent
neural networks to further exploit the potential of neural networks in SfM.
Specifically, our neural optimizer alternately updates the depth and camera
poses through iterations to minimize a feature-metric cost, and two gated
recurrent units iteratively improve the results by tracing historical
information. In this way, our network is a gradient-free zeroth-order optimizer
designed for SfM and can be applied to both supervised and self-supervised SfM.
Extensive experimental results demonstrate that our method outperforms previous
methods and is more efficient in computation and memory consumption than
cost-volume-based methods. In particular, our self-supervised method
outperforms previous supervised methods on the KITTI and ScanNet datasets. Our
source code is available at https://github.com/aliyun/dro-sfm.
