Occupancy Flow Fields for Motion Forecasting in Autonomous Driving

چکیده

We propose Occupancy Flow Fields, a new representation for motion forecasting of multiple agents, an important task in autonomous driving. Our is spatio-temporal grid with each cell containing both the probability being occupied by any agent, and two-dimensional flow vector representing direction magnitude that cell. method successfully mitigates shortcomings two most commonly-used representations forecasting: trajectory sets occupancy grids. Although grids efficiently represent probabilistic location many agents jointly, they do not capture agent lose identities. To this end, we deep learning architecture generates Fields help trace loss establishes consistency between predictions. demonstrate effectiveness our approach using three metrics on prediction, estimation, ID recovery. In addition, introduce problem predicting speculative which are currently-occluded may appear future through dis-occlusion or entering field view. report experimental results large in-house driving dataset public INTERACTION dataset, show model outperforms state-of-the-art models.

Safe Motion Planning for Autonomous Driving

Self-driving cars have the potential to revolutionize transportation by making it cheaper, safer, and more efficient. In this thesis we describe a novel motion planning system, which translates high-level navigation goals into low-level actions for controlling a vehicle. Specifically, the motion planning system is responsible for choosing at each time step an appropriate velocity and steering a...

Toward Safe and Human-like Motion Generation for Autonomous Driving

1. Project Overview In order to drive safely and efficiently, autonomous vehicles need to understand the behavior of others, predict their future motions and plan desirable motions which are safe and human-like to execute. In this project, we tackled motion prediction and planning together as a motion generation problem to achieve accurate comprehension of others, as well as safe and human-like...

A New Algorithm for Load Flow Analysis in Autonomous Networks

In this paper, a novel algorithm for the load flow analysis problem in an islanded microgrid is proposed. The problem is modeled without any slack bus by considering the steady state frequency as one of the load flow variables. To model different control modes of DGs, such as droop, PV and PQ, in an islanded microgrid, a new formula for load flow equations is proposed. A hybrid optimization alg...
