摘要：Problem to be solved: to provide a passenger detecting device and an elevatorsystem capable of suppressing the erroneous detection of passengers even when theinternal environment of the car changes.In the passenger detection device (4) or theelevator system (1), the input section (12) receives the input of the first and secondimages.The first image is photographed on a first camera (11a) provided in the cage(2).The second image is photographed from a different direction from the first camera(11a) to the second camera (11b) provided in the cage (2).The first and second imagesinclude a floor surface (5) of the cage (2).The conversion part (13) performs the
homography conversion of the first image and the second image so that the range of thefloor surface (5) of the car (2) of the first image and the floor plane (5) of the cage (2) ofthe second image overlap each other.The determination unit (16) determines whether ornot the passenger inside the cage (2) is based on the difference between the range of thefloor surface (5) of the cage (2) overlapped with each other of the first and secondimages after the homography conversion.
