The invention belongs to the spaceflight remote sensor electron system technical field, and relates to a dual-video processor synchronization imaging method; the method can satisfy video processor simultaneous imaging requirements by image fusion; two devices can mutually send station clock and line synchronizing signals so as to allow the two devices to synchronically work; in the prior art, another signal processor sends synchronization imaging signals to two video processors so as to control the two video processors to simultaneously work; the dual-video processor synchronization imaging method can omit one single unit, thus reducing system scale and cost. 本发明属于航天遥感器电子系统技术领域，涉及种两台视频处理器同步成像的方法。本发明既解决了图像融合对视频处理器同时成像的要求，该设计通过两台设备之间互发主时钟和行同步信号来实现两台设备同步工作。又解决了传统设计的通过另外台信号处理器向两台视频处理器发送同步成像信号，从而控制两台视频处理器同时工作的方法。本发明减少了台单机设备，从而减小了系统的规模以及成本。
