Abstract
A method for performing frame synchronization control on a first camera and a second camera of a self-propelled device includes: sending, in response to capturing a first image frame, a synchronization instruction to a controller of the self-propelled device; in response to receiving the synchronization instruction, determining a sending timepoint of a frame synchronization signal based on a time offset relative to a timepoint of capturing the first image frame; and sending the frame synchronization signal to the second camera at the sending timepoint, thereby controlling the second camera to capture a second image frame.
