CADSim: Robust and Scalable in-the-wild 3D Reconstruction for Controllable Sensor Simulation

no code implementations2 Nov 2023 Jingkang Wang, Sivabalan Manivasagam, Yun Chen, Ze Yang, Ioan Andrei Bârsan, Anqi Joyce Yang, Wei-Chiu Ma, Raquel Urtasun

To tackle these issues, we present CADSim, which combines part-aware object-class priors via a small set of CAD models with differentiable rendering to automatically reconstruct vehicle geometry, including articulated wheels, with high-quality appearance.

Towards Zero Domain Gap: A Comprehensive Study of Realistic LiDAR Simulation for Autonomy Testing

no code implementations ICCV 2023 Sivabalan Manivasagam, Ioan Andrei Bârsan, Jingkang Wang, Ze Yang, Raquel Urtasun

We leverage this setting to analyze what aspects of LiDAR simulation, such as pulse phenomena, scanning effects, and asset quality, affect the domain gap with respect to the autonomy system, including perception, prediction, and motion planning, and analyze how modifications to the simulated LiDAR influence each part.

Deep Multi-Task Learning for Joint Localization, Perception, and Prediction

no code implementations CVPR 2021 John Phillips, Julieta Martinez, Ioan Andrei Bârsan, Sergio Casas, Abbas Sadat, Raquel Urtasun

Over the last few years, we have witnessed tremendous progress on many subtasks of autonomous driving, including perception, motion forecasting, and motion planning.

Asynchronous Multi-View SLAM

no code implementations17 Jan 2021 Anqi Joyce Yang, Can Cui, Ioan Andrei Bârsan, Raquel Urtasun, Shenlong Wang

Existing multi-camera SLAM systems assume synchronized shutters for all cameras, which is often not the case in practice.

Pit30M: A Benchmark for Global Localization in the Age of Self-Driving Cars

no code implementations23 Dec 2020 Julieta Martinez, Sasha Doubov, Jack Fan, Ioan Andrei Bârsan, Shenlong Wang, Gellért Máttyus, Raquel Urtasun

We are interested in understanding whether retrieval-based localization approaches are good enough in the context of self-driving vehicles.

Learning to Localize Through Compressed Binary Maps

no code implementations CVPR 2019 Xinkai Wei, Ioan Andrei Bârsan, Shenlong Wang, Julieta Martinez, Raquel Urtasun

One of the main difficulties of scaling current localization systems to large environments is the on-board storage required for the maps.

Learning to Localize Using a LiDAR Intensity Map

no code implementations20 Dec 2020 Ioan Andrei Bârsan, Shenlong Wang, Andrei Pokrovsky, Raquel Urtasun

In this paper we propose a real-time, calibration-agnostic and effective localization system for self-driving cars.

Robust Dense Mapping for Large-Scale Dynamic Environments

no code implementations7 May 2019 Ioan Andrei Bârsan, Peidong Liu, Marc Pollefeys, Andreas Geiger

We use both instance-aware semantic segmentation and sparse scene flow to classify objects as either background, moving, or potentially moving, thereby ensuring that the system is able to model objects with the potential to transition from static to dynamic, such as parked cars.
