Title:
TRAFFIC PREDICTION BASED ON MAP IMAGES FOR AUTONOMOUS DRIVING
Document Type and Number:
WIPO Patent Application WO/2018/232681
Kind Code:
A1
Abstract:
A computer-implemented method for operating an autonomous driving vehicle, a non-transitory machine-readable medium, and a data processing system are provided. In response to perception data perceiving a driving environment surrounding an ADV, a map image of a map covering a location associated with the driving environment is obtained. An image recognition is performed on the map image to recognize one or more objects from the map image. An object may represent a particular road, a building structure (e.g., a parking lot, an intersection, or a roundabout). One or more features are extracted from the recognized objects, where the features may indicate or describe the traffic condition of the driving environment. Behaviors of one or more traffic participants perceived from the perception data are predicted based on the extracted features. A trajectory for controlling the ADV to navigate through the driving environment is planned based on the predicted behaviors of the traffic participants. A traffic participant can be a vehicle, a cyclist, or a pedestrian.
