Gated2Gated: Self-Supervised Depth Estimation from Gated Images

1 code implementation CVPR 2022 Amanpreet Walia, Stefanie Walz, Mario Bijelic, Fahim Mannan, Frank Julca-Aguilar, Michael Langer, Werner Ritter, Felix Heide

Gated cameras hold promise as an alternative to scanning LiDAR sensors with high-resolution 3D depth that is robust to back-scatter in fog, snow, and rain.

ZeroScatter: Domain Transfer for Long Distance Imaging and Vision through Scattering Media

1 code implementation CVPR 2021 Zheng Shi, Ethan Tseng, Mario Bijelic, Werner Ritter, Felix Heide

Most of today's supervised imaging and vision approaches, however, rely on training data collected in the real world that is biased towards good weather conditions, with dense fog, snow, and heavy rain as outliers in these datasets.

Seeing Around Street Corners: Non-Line-of-Sight Detection and Tracking In-the-Wild Using Doppler Radar

1 code implementation CVPR 2020 Nicolas Scheiner, Florian Kraus, Fangyin Wei, Buu Phan, Fahim Mannan, Nils Appenrodt, Werner Ritter, Jürgen Dickmann, Klaus Dietmayer, Bernhard Sick, Felix Heide

In this work, we depart from visible-wavelength approaches and demonstrate detection, classification, and tracking of hidden objects in large-scale dynamic environments using Doppler radars that can be manufactured at low-cost in series production.

Benchmarking Image Sensors Under Adverse Weather Conditions for Autonomous Driving

no code implementations6 Dec 2019 Mario Bijelic, Tobias Gruber, Werner Ritter

Adverse weather conditions are very challenging for autonomous driving because most of the state-of-the-art sensors stop working reliably under these conditions.

Learning Super-resolved Depth from Active Gated Imaging

no code implementations5 Dec 2019 Tobias Gruber, Mariia Kokhova, Werner Ritter, Norbert Haala, Klaus Dietmayer

Environment perception for autonomous driving is doomed by the trade-off between range-accuracy and resolution: current sensors that deliver very precise depth information are usually restricted to low resolution because of technology or cost limitations.

Pixel-Accurate Depth Evaluation in Realistic Driving Scenarios

1 code implementation21 Jun 2019 Tobias Gruber, Mario Bijelic, Felix Heide, Werner Ritter, Klaus Dietmayer

This work introduces an evaluation benchmark for depth estimation and completion using high-resolution depth measurements with angular resolution of up to 25" (arcsecond), akin to a 50 megapixel camera with per-pixel depth available.

Seeing Through Fog Without Seeing Fog: Deep Multimodal Sensor Fusion in Unseen Adverse Weather

1 code implementation CVPR 2020 Mario Bijelic, Tobias Gruber, Fahim Mannan, Florian Kraus, Werner Ritter, Klaus Dietmayer, Felix Heide

The fusion of multimodal sensor streams, such as camera, lidar, and radar measurements, plays a critical role in object detection for autonomous vehicles, which base their decision making on these inputs.
