Abstract
A method includes obtaining, by a processing device, input data derived from a set of sensors associated with an autonomous vehicle (AV). The input data includes camera data and radar data. The method further includes extracting, by the processing device from the input data, a plurality of sets of bird's-eye view (BEV) features. Each set of BEV features corresponds to a respective timestep. The method further includes generating, by the processing device from the plurality of sets of BEV features, an object flow for at least one object. Generating the object flow includes performing at least one of: multi-frame temporal aggregation or multi-frame dense motion estimation. The method further includes causing, by the processing device, a driving path of the AV to be modified in view of the object flow.
