Convolutions for Spatial Interaction Modeling

CVPR 2022poster

In many different fields interactions between objects play a critical role in determining their behavior. Graph neural networks (GNNs) have emerged as a powerful tool for modeling interactions, although often at the cost of adding considerable complexity and latency. In this paper, we consider the p…

LaserFlow: Efficient and Probabilistic Object Detection and Motion Forecasting

RA-L 2021

In this work, we present LaserFlow, an efficient method for 3D object detection and motion forecasting from LiDAR. Unlike the previous work, our approach utilizes the native range view representation of the LiDAR, which enables our method to operate at the full range of the sensor in real-time witho

Temporally-Continuous Probabilistic Prediction using Polynomial Trajectory Parameterization

IROS 2021poster

A commonly-used representation for motion prediction of actors is a sequence of waypoints (comprising positions and orientations) for each actor at discrete future time-points. While regressing waypoints is simple and flexible, it can exhibit unrealistic higher-order derivatives (such as acceleratio…

LiRaNet: End-to-End Trajectory Prediction using Spatio-Temporal Radar Fusion

CoRL 2020

In this paper, we present LiRaNet, a novel end-to-end trajectory prediction method which utilizes radar sensor information along with widely used lidar and HD maps. Automotive radar provides rich, complementary information, allowing for longer range vehicle detection as well as instantaneous radial

LaserNet: An Efficient Probabilistic 3D Object Detector for Autonomous Driving

CVPR 2019poster

In this paper, we present LaserNet, a computationally efficient method for 3D object detection from LiDAR data for autonomous driving. The efficiency results from processing LiDAR data in the native range view of the sensor, where the input data is naturally compact. Operating in the range view invo…
