The invention discloses an automatic driving multi-sensor synchronous playback method and system, and the method comprises the steps: deploying an AVB transmitting end on a radar collection device and an image collection device, and deploying an AVB receiving end on an intelligent driving controller; the radar acquisition device and the image acquisition device send multi-sensor information, and set a synchronous playback timestamp and a period of each sensor according to a sensor sampling period; meanwhile, the AVB sending end sets an AVB CRF transmission format, and the CRF bears a synchronous playback timestamp and a period of each sensor; the intelligent driving controller receives multi-sensor signal data and synchronous playback timestamp information and period of each sensor; the intelligent driving controller is provided with a playback end, the playback end is provided with a plurality of playback nodes, and multi-sensor synchronous playback is started according to the signal period of each sensor and the timestamp needing synchronous playback. Through AVB time synchronization and CRF sending service, standardized processing of automatic driving multi-sensor synchronous playback is realized.
本发明公开了一种自动驾驶多传感器同步回放方法及系统，雷达采集设备和图像采集设备上部署AVB发送端，智驾控制器上部署AVB接收端；雷达采集设备和图像采集设备发送多传感器信息，并根据传感器采样周期设定每一种传感器的同步回放时间戳及周期；同时AVB发送端设定AVB CRF传输格式，CRF承载每一种传感器的同步回放时间戳及周期；智驾控制器接收多传感器信号数据，以及每一种传感器的同步回放时间戳信息及周期；智驾控制器设置回放端，回放端部署多个回放节点，分别按照每一种传感器的信号周期，以及需要同步回放的时间戳，启动多传感器同步回放。本发明通过AVB时间同步及CRF发送服务，实现自动驾驶多传感器同步回放的标准化处理。
