  • Publication number: 20250213980
    Abstract: In a method for collision event determination, a first estimated trajectory that a target object is expected to follow during a next movement period is obtained. A second estimated trajectory that a collision object is expected to follow during the next movement period is obtained. A spatial positional relationship between the first estimated trajectory and the second estimated trajectory is determined to satisfy a reference collision condition. Based on the determination that the spatial positional relationship between the first estimated trajectory and the second estimated trajectory satisfies the reference collision condition, a candidate collision space that indicates a space through which the target object is not allowed to move is determined. A collision event is determined to occur between the target object and the collision object when a plurality of candidate object positions on the first estimated trajectory include a target object position in the candidate collision space.
