要旨:
Progress towards advanced systems for assisted and autonomous driving is
leveraging recent advances in recognition and segmentation methods. Yet, we are
still facing challenges in bringing reliable driving to inner cities, as those
are composed of highly dynamic scenes observed from a moving platform at
considerable speeds. Anticipation becomes a key element in order to react
timely and prevent accidents. In this paper we argue that it is necessary to
predict at least 1 second and we thus propose a new model that jointly predicts
ego motion and people trajectories over such large time horizons. We pay
particular attention to modeling the uncertainty of our estimates arising from
the non-deterministic nature of natural traffic scenes. Our experimental
results show that it is indeed possible to predict people trajectories at the
desired time horizons and that our uncertainty estimates are informative of the
prediction error. We also show that both sequence modeling of trajectories as
well as our novel method of long term odometry prediction are essential for
best performance.
