Title
(EN) Multi-sensor data synchronization system and image data synchronization method
(ZH) 多传感器数据同步系统以及图像数据同步方法
Abstract
(EN)
The invention provides a multi-sensor data synchronization system and an image data synchronization method. The system comprises a host and a plurality of sensors which are connected with the host; the host is used for collecting data input by the plurality of the sensors and an image acquisition device; the plurality of the sensors include a first sensor, a second sensor and a third sensor; the first sensor is connected with a vehicle body CAN bus; the second sensor is connected with a private CAN bus; the third sensor comprises a signal end and a data end; the signal end is connected with the vehicle body CAN bus, and is used for outputting a frame signal; the data end is connected with the host through a data line, and outputs data to the host; and the vehicle body CAN bus and the private CAN bus are connected with the host through the same data converter, so that the data input to the host can be synchronized. The delay of the data in a transmission process can be greatly shortened, and the instantaneity of the data is improved; and moreover, the collected data can be subjected to time stamp unification.
