The invention discloses a dual-event camera synchronous acquisition system and a noise event suppression method, and belongs to the field of image acquisition and image processing. According to the invention, two event cameras of the same model, an external trigger board and an optical assembly are utilized to establish a high-precision time synchronization acquisition system, and acquisition of the two event cameras is controlled through pulse signals of the external trigger board to achieve microsecond-level timestamp alignment; the method comprises the following steps of: accumulating two groups of collected event stream signals into event frame images according to a period of time, selecting a plurality of corresponding characteristic event points on the two groups of event frame images, solving to obtain a perspective transformation projection matrix of two event camera view fields, and finishing space alignment of the two groups of event streams. And in the two groups of event streams after space-time a
