1. A method for realizing shutter synchronization of a camera, wherein the camera comprises a plurality of sensors; shutter types of the plurality of sensors are different; the method comprises:
acquiring a periodic synchronization reference signal and a synchronization signal corresponding to each of the plurality of sensors; and
adjusting, with the synchronization reference signal as a reference, at least one of synchronization signal delays or exposure delays of the plurality of sensors to align exposure areas corresponding to the plurality of sensors;
wherein the plurality of sensors comprise a first sensor and a second sensor; the synchronization signal comprises: a first synchronization signal corresponding to the first sensor and a second synchronization signal corresponding to the second sensor; and
wherein a frame period and an exposure duration of a first synchronization signal of an i-th frame are same as a frame period and an exposure duration of a second synchronization signal of an i-th frame, wherein i is a positive integer; an exposure starts from a rising edge of a first synchronization signal of each frame, and an exposure starts after a preset exposure delay is executed on a second synchronization signal of each frame.
