The invention discloses a multi-sensor space-time synchronization and traffic scheduling device and method based on vehicle-road cooperation, relates to the technical field of road traffic, changes the data aggregation mode of subsystems, restrains the distributed subsystems under the same time axis, and provides preconditions for data fusion of multi-sensing equipment. Through carrying a multi-sensor space-time synchronization and traffic driving scheduling device based on a vehicle-road cooperation global area network, hard touch exposure control of a camera and cooperation of the camera and a light supplement lamp in different light environments are realized, and a frame synchronization guarantee is provided for perception data fusion of a mechanical laser radar and the camera. And the reliability of the sensing data source in different light environments is ensured, and the effective recall rate of the sensing data is enhanced. Through carrying a multi-sensor space-time synchronization and traffic driving scheduling device based on a vehicle-road cooperation global network, traffic light state information can be uploaded to a cloud server through a network interface, and scheduling information of a node unit with a control right can also be received, thereby realizing traffic flow scheduling.

    本发明公开了一种基于车路协同的多传感器时空同步及交通调度装置及方法,涉及道路交通技术领域,改变该子系统的数据汇聚方式,将分布式各子系统约束在同一个时间轴下,为多感知设备的数据融合提供先决条件。通过搭载基于车路协同全域网下的多传感器时空同步及交通驱动调度的装置实现相机的硬触曝光控制,以及相机和补光灯在不同光线环境下的协同配合,为机械激光雷达与相机的感知数据融合提供帧同步的保障,并确保了不同光线环境下感知数据源的可靠性,增强感知数据的有效召回率。通过搭载基于车路协同全域网下的多传感器时空同步及交通驱动调度的装置,可通过网络接口向云端服务器上传红绿灯状态信息,也可接收具有控制权节点单元的调度信息,实现交通流的调度。
