Query: Unsupervised Visible-light Images Guided Cross-Spectrum Depth Estimation
  from Dual-Modality Cameras   Cross-spectrum depth estimation aims to provide a depth map in all
illumination conditions with a pair of dual-spectrum images. It is valuable for
autonomous vehicle applications when the vehicle is equipped with two cameras
of different modalities. However, images captured by different-modality cameras
can be photometrically quite different. Therefore, cross-spectrum depth
estimation is a very challenging problem. Moreover, the shortage of large-scale
open-source datasets also retards further research in this field. In this
paper, we propose an unsupervised visible-light image guided cross-spectrum
(i.e., thermal and visible-light, TIR-VIS in short) depth estimation framework
given a pair of RGB and thermal images captured from a visible-light camera and
a thermal one. We first adopt a base depth estimation network using RGB-image
pairs. Then we propose a multi-scale feature transfer network to transfer
features from the TIR-VIS domain to the VIS domain at the feature level to fit
the trained depth estimation network. At last, we propose a cross-spectrum
depth cycle consistency to improve the depth result of dual-spectrum image
pairs. Meanwhile, we release a large dual-spectrum depth estimation dataset
with visible-light and far-infrared stereo images captured in different scenes
to the society. The experiment result shows that our method achieves better
performance than the compared existing methods. Our datasets is available at
