  • Patent number: 11946749
    Abstract: Among other things, techniques are described for driver data guided spatial planning. A spatial structure is generated comprising a plurality of nodes connected by edges. At least some of the nodes and edges represent a path to navigate a vehicle from a first point to a second point. Edges of the spatial structure are labeled as useful based on a distance metric. The spatial structure is pruned by removing one or more edges from the spatial structure according to a respective label of the edges, wherein an extent of the removal is based on a predetermined graph size, a predetermined performance, or any combinations thereof to obtain a pruned graph. A path from the first point to the second point on the pruned graph is identified and the vehicle is navigated in accordance with the path from the first point to the second point on the pruned graph.

  • Patent number: 11912271
    Abstract: Among other things, techniques are described for predicting how an agent (e.g., a vehicle, bicycle, pedestrian, etc.) will move in an environment based on prior movement, the road network, the surrounding objects and/or other relevant environmental factors. One trajectory prediction technique involves generating a probability map for an agent's movement. Another trajectory prediction technique involves generating a trajectory lattice, for an agent's movement. In addition, a different trajectory prediction technique involves multi-modal regression where a classifier (e.g., a neural network) is trained to classify the probability of a number of (learned) modes such that each model produces a trajectory based on the current input.

  • Publication number: 20230382427
    Abstract: Provided are methods for motion prediction in an autonomous vehicle using fused synthetic and camera images. The method can include obtaining data pairs, each of which reflects data corresponding to a synthetic image representing a birds-eye-view of an area around a vehicle and identifying an object, and data corresponding to a camera image depicting the object. A machine learning model can be trained based on the data pairs to result in a trained model that predicts motion of the object within the data pair based on the synthetic image and camera image in the data pair. Systems and computer program products are also provided.
