Occupancy Flow Fields for Motion Forecasting in Autonomous Driving. (arXiv:2203.03875v1 [cs.RO])

We propose Occupancy Flow Fields, a new representation for motion forecasting
of multiple agents, an important task in autonomous driving. Our representation
is a spatio-temporal grid with each grid cell containing both the probability
of the cell being occupied by any agent, and a two-dimensional flow vector
representing the direction and magnitude of the motion in that cell. Our method
successfully mitigates shortcomings of the two most commonly-used
representations for motion forecasting: trajectory sets and occupancy grids.
Although occupancy grids …
