The invention discloses a parking method and system based on quay crane recognition through radar ranging, a server and a medium. According to the method, a laser radar is utilized for acquiring pointclouds of determined barriers nearby a vehicle to determine the advancing position of the vehicle, by recognizing a feature point cloud of a beam right in front of the vehicle, tracking and ranging are conducted on the beam, in combination with beam feature ranging in the recognized point cloud and a speed acquired by a vehicle body CAN bus, the target parking distance is calculated, and the purpose of describing the advancing position of the vehicle in real time is achieved; compared with an existing precise parking technology, it is not necessary to lay road signs manually, continuous and real-time measurement can be achieved, and the environment universality is good.
