The embodiment of the invention relates to the technical field of data processing, and discloses a data synchronization system and method. The method comprises the steps: a controller is used for obtaining real-time sensing data transmitted by a plurality of sensing modules, and recording the obtaining time of the real-time sensing data; an exposure trigger signal is generated, the trigger time of the exposure trigger signal is recorded, and the exposure trigger signal is sent to the camera module; the obtaining time and the triggering time are recorded time by taking a real-time clock as a clock source; a camera module is used for generating image data according to the exposure trigger signal and recording the generation time of the image data; the generation time is time recorded by taking a real-time clock as a clock source; and a data fusion module is used for matching the real-time sensing data and the image data according to the acquisition time, the triggering time and the generation time, and performing data fusion processing according to a matching result. According to the embodiment of the invention, the accuracy of data processing is improved.

    本发明实施例涉及数据处理技术领域,公开了一种数据同步系统,该方法包括:控制器用于获取多个传感模块发送的实时传感数据,记录实时传感数据的获取时间;生成曝光触发信号,记录曝光触发信号的触发时间,将曝光触发信号发送给摄像模块;获取时间及触发时间是以实时时钟为时钟源所记录的时间;摄像模块用于根据曝光触发信号生成图像数据,记录图像数据的生成时间;生成时间为以实时时钟为时钟源所记录的时间;数据融合模块用于根据获取时间、触发时间以及生成时间对实时传感数据及图像数据进行匹配,并根据匹配结果进行数据融合处理。本发明实施例提高了数据处理的精准度。
