(54)METHOD FOR ACQUIRING TRAFFIC STATE, RELEVANT APPARATUS, ROADSIDE DEVICE AND CLOUD CONTROL PLATFORM


(57) A method and apparatus for acquiring a traffic state, an electronic device, a computer-readable storage medium, a computer program product, a roadside device and a cloud control platform are provided. An implementation of the method may include: acquiring monitoring data from at least one camera in a camera group, wherein the at least one camera is capable of shooting object moving states at different road sections or a same road section of a target intersection; determining, based on the monitoring data acquired from each camera, a moving trajectory of a reference object recorded by the each camera in the at least one camera; then fusing moving trajectories of the reference object to obtain a completed trajectory; and finally predicting an indication state of a signal light on a corresponding road based on a travel direction of the corresponding road, the completed trajectory being located on the corresponding road.
