1. A detection system for detecting an entrance of an aircraft, the detection system comprising:
a passenger boarding bridge connected to a terminal building;
a camera provided on the passenger boarding bridge; and
an image processor that detects the entrance of the aircraft from a captured image captured by the camera, wherein
the image processor includes:
a search area image generator that generates a search area image by demarcating a predetermined area that includes a part of the captured image, and performs projective transformation on a virtual plane in the predetermined area of the captured image; and
a search performer that performs a search to determine whether or not the entrance is present within the search area image,
the search area image generator shifts the predetermined area on the captured image from one side toward the other side of the aircraft in a direction of an aircraft axis of the aircraft to sequentially generate the search area image, and
the search performer repeatedly performs the search while changing the search area image by using a plurality of the search area images that are sequentially generated.
