The invention relates to a multi-sensor data synchronization method, system and device and an automobile, and the method comprises the steps: starting a local timing module of the automobile when the automobile is powered on, and obtaining the local timing time; the local timing time is transmitted to a first sensor, supporting time synchronization, of the automobile, so that the first sensor marks a first timestamp on the collected first data according to the local timing time; when second data collected by a second sensor which does not support time synchronization is obtained, marking a second timestamp on the second data by using local timing time; after the first data is received, the first data and the second data are synchronized by using the first timestamp of the first data and the second timestamp of the second data. According to the method, the timestamps of the data of the two sensors are marked by using the same local timing time, and data alignment is realized, so that the problem that the data of the sensors which do not support time synchronization cannot be synchronized is solved.
本申请涉及一种多传感器的数据同步方法、系统、设备和一种汽车,该方法包括:在汽车通电时,启动汽车的本地计时模块,得到本地计时时间;将本地计时时间传输给汽车的支持时间同步的第一传感器,以使第一传感器按照本地计时时间给采集的第一数据打上第一时间戳;在获取到不支持时间同步的第二传感器采集的第二数据时,使用本地计时时间为第二数据打上第二时间戳;在接收到第一数据后,使用第一数据的第一时间戳与第二数据的第二时间戳同步第一数据与第二数据。本申请让两种传感器的数据的时间戳使用同一个本地计时时间进行标记,实现了数据对齐,因此解决了不支持时间同步的传感器的数据无法同步的问题。
