A storage (321) stores a first image of an object (122) in an image-capturing target region (121) and a second image, the first image being captured by a first imaging device (111, 311), and the second image being captured by a second imaging device (112, 312) by use of a reflected electromagnetic wave from the image-capturing target region, using an electromagnetic source (113, 313) that radiates an electromagnetic wave onto the image-capturing target region. When a position of a strongly reflective region in the second image corresponds to a prescribed position in the second image, a position estimator (327) estimates a position of the object on the basis of the first image and complementary information that complements an image of the strongly reflective region. |
