Patent number: 11987265Abstract: A system obtains scene context data characterizing the environment. The scene context data includes data that characterizes a trajectory of an agent in a vicinity of a vehicle up to a current time point. The system identifies a plurality of initial target locations, and generates, for each of a plurality of target locations that each corresponds to one of the initial target locations, a respective predicted likelihood score that represents a likelihood that the target location will be an intended final location for a future trajectory of the agent. For each target location in a first subset of the target locations, the system generates a predicted future trajectory for the agent given that the target location is the intended final location for the future trajectory. The system further selects, as likely future trajectories of the agent, one or more of the predicted future trajectories.Type: GrantFiled: July 28, 2021Date of Patent: May 21, 2024Assignee: Waymo LLCInventors: Hang Zhao, Jiyang Gao, Chen Sun, Yi Shen, Yuning Chai, Cordelia Luise Schmid, Congcong Li, Benjamin Sapp, Dragomir Anguelov, Tian Lan, Yue Shen
