Abstract: The present disclosure relates to optical flow estimation methods and apparatuses. One example method includes obtaining a first image frame and a second image frame, where the first image frame and the second image frame are any two adjacent image frames in an image sequence, and the image sequence is obtained by photographing a target scene. A first event frame is obtained, where the first event frame is used to describe a luminance change of the target scene within a time period from the first image frame to the second image frame. A target optical flow is determined based on the first image frame, the second image frame, and the first event frame, where the target optical flow is an optical flow from the first image frame to a target moment, and the target moment is any moment between the first image frame and the second image frame.
