9. A vehicle detection system comprising:
a mobile object that includes a far-infrared camera; and
a server that is able to communicate with the mobile object, wherein
the mobile object captures a second image at a time different from the time at which a parked vehicle has been imaged at the same position at which the parked vehicle has been imaged,
the server includes a processor configured to determine whether the parked vehicle is used as a shelter based on a first image which is included in an image captured by the far-infrared camera and which is obtained by imaging the vehicle and surroundings of the vehicle,
the far-infrared camera is able to measure a temperature of a subject as at least a part of the first image, and
the processor is configured to
evaluate that there is a higher likelihood that the vehicle is used as a shelter when it is recognized from the image from the far-infrared camera that at least a part of the vehicle has a temperature different from that of surroundings than when it is recognized that at least a part of the vehicle does not have a temperature different from that of the surroundings, and
acquire the second image and to evaluate that there is a higher likelihood that the vehicle is used as a shelter when the vehicle is not included in the second image and an object installed at the position at which the vehicle is parked is included in the second image than when the object is not included in the second image.
