Vehicle-road collaborative navigation system and method with high anti-interference capability

The invention discloses a vehicle-road collaborative navigation system and method with high anti-interference capability. The system comprises a plurality of beacon units which are arranged at equal intervals along the longitudinal direction of a lane and a beacon searching unit which is arranged on a vehicle, wherein the beacon unit is used for emitting flickering light and emitting response pulses in a delayed manner after receiving ultrasonic pulses emitted by the beacon seeking unit; the beacon searching unit measures the distance between the vehicle and the beacon units in an ultrasonic distance measuring mode and controls the beacon units to be sequentially turned on and turned off from near to far according to the distance between the vehicle and the beacon units, and it is always guaranteed that only the nearest beacon unit in front of the vehicle in a lane works; and acquiring the position of the beacon unit according to the difference result of the front scene image, and guiding the vehicle to run b
