Abstract: Provided are a passenger detecting device and an elevator system with which it is possible to suppress the false detection of a passenger even when the environment inside a car changes. An input unit (12) in this passenger detecting device (4) or elevator system (1) receives the inputs of a first image and a second image. The first image is captured by a first camera (11a) provided in a car (2). The second image is captured from a different direction from the first camera (11a) by a second camera (11b) provided in the car (2). The first image and the second image include the floor surface (5) of the car (2). A transforming unit (13) performs homographic transformation on the first image and the second image so that the range of the floor surface (5) of the car (2) in the first image and the range of the floor surface (5) of the car (2) in the second image overlap. A determining unit (16) determines the presence or absence of a passenger inside the car (2) on the basis of the difference between the overlapping ranges of the floor surface (5) of the car (2) in the first image and the second image after the homographic transformation.
