Abstract

A computer-implemented method comprises sensing an environment of the ego-agent that includes at least one other agent. The method predicts possible behaviors of the at least one other agent based on the sensed environment, and plans trajectories of the ego-agent for each possible behavior of the at least one other agent to generate a set of planned trajectories. The method proceeds with determining an actual trajectory of the ego-agent, and comparing the determined actual trajectory of the ego-agent with each of the planned trajectories of the ego-agent and determining a planned trajectory with a largest similarity to the actual trajectory of the ego-agent. Subsequently, a perceived situation as perceived by the ego-agent based on a particular predicted possible behavior of the predicted possible behaviors corresponding to the planned trajectory with the largest similarity is determined. The method executes an action in an assistance system based on the determined perceived situation.
