1. A vehicle recognition system for recognizing a vehicle in a closed space, the vehicle recognition system comprising:
a storage device that stores a camera image acquired by a camera installed in the closed space, opening/closing information on a shutter provided at an entrance/exit for a vehicle in the closed space, information on an inside illuminance indicating an illuminance in a shooting space of the camera inside the closed space, and information on an outside illuminance indicating an illuminance outside the closed space; and
a processor is configured to perform a recognition processing of a vehicle included in the camera image,
wherein, in the recognition processing, the processor is configured to:
determine whether the shutter is opened or not based on the opening/closing information on the shutter;
determine whether or not the outside illuminance is higher than the inside illuminance based on the information on the outside illuminance and the information on the inside illuminance; and
perform brightness correction processing for correcting brightness of the camera image when it is determined that the shutter is opened and the outside illuminance is higher than the inside illuminance.
