1. A virtual barrier gate control method, comprising:
generating a first control signal on the basis of a starting signal; and
projecting, according to the first control signal, a three-dimensional holographic image with a specified shape to a preset position to serve as a virtual barrier gate;
wherein a specific text or pattern is contained in the three-dimensional holographic image;
the method further comprises:
switching the specific text or pattern according to a preset rule;
collecting image data in a first specified region before the preset position in a direction in which an object moves towards the preset position, and identifying the image data to obtain an attribute of a target object in the first specified region; and
generating a second control signal according to the attribute of the target object, and modifying the three-dimensional holographic image projected to the preset position according to the second control signal;
wherein the target object is a vehicle;
the attribute comprises at least one of: a license plate number, a vehicle model and a color; and
the before collecting image data in the first specified region before the preset position in the direction in which an object moves towards the preset position, the method further comprises:
collecting image data in a second specified region before the preset position in a direction in which the vehicle is driven towards the preset position, and processing the image data to obtain driving data of the vehicle in the second specified region; and
generating an alarm signal according to the driving data of the vehicle, and giving an alarm according to the alarm signal.
