Abstract
A light emitting apparatus recognition system includes a light emitting apparatus, an image capturing apparatus, a recognition apparatus, and an electromagnetic wave emitting element. The light emitting apparatus includes a light source that blinks on the basis of identification information unique to the light emitting apparatus and an electromagnetic wave receiving element. The image capturing apparatus captures an image of light emitted by the light source of the light emitting apparatus. The recognition apparatus recognizes the light emitting apparatus on the basis of the light appearing in the image captured by the image capturing apparatus. The electromagnetic wave emitting element emits an electromagnetic wave from the image capturing apparatus or a vicinity of the image capturing apparatus. The electromagnetic wave receiving element receives the electromagnetic wave emitted by the electromagnetic wave emitting element.
