The invention discloses a vehicle-road cooperation anti-collision early warning system and method. The system comprises a vehicle-mounted equipment end, an intelligent mobile terminal worn or carried by pedestrians, a roadside communication unit and edge computing equipment in direct communication connection with the roadside communication unit. The roadside communication unit comprises a roadside signaling communication module, a differential positioning processing module and a video acquisition module; the edge computing device comprises a target detection module, a coordinate conversion module, a fusion positioning module, a trajectory prediction module and a collision analysis module. According to the invention, positioning information reported by the vehicle-mounted equipment terminal and the intelligent mobile terminal in real time and identification positioning information obtained by the target detection module and the coordinate conversion module are comprehensively adopted, and reasonable optimization processing is carried out by using the fusion positioning module, so that comprehensive identification and positioning of a target can be realized, missing detection and false detection are effectively avoided, and the positioning accuracy is improved. Especially for pedestrians who do not carry intelligent mobile terminals, the safety and effectiveness of collision early warning are guaranteed.
