Abstract
The present application provides a position determination device and a position determination method, which can determine a position without using positioning. The position determination device includes: a photographic image acquisition unit (40) that acquires a photographic image (A1) captured by a camera (30) provided on a moving body (1); a position information acquisition unit (50) that acquires position information (G) representing a position indicated by a specified object (F) indicating a position when the specified object (F) is captured in the photographic image (A1); and a viewpoint axis position determination unit (52) that determines a position to which a viewpoint axis (K) of the camera (30) points based on the position information (G) and a positional relationship between the specified object (F) and the viewpoint axis (K) in the photographic image (A1).
