Provided is a moveable spectrum measuring apparatus capable of improving discrimination precision of a measuring object on the basis of observation data from a spectrum sensor mounted on a movable apparatus such as a vehicle. A measuring object and a reference body are irradiated with ambient light. A spectrum acquiring device acquires measuring object data indicating the spectrum of the measuring object, and reference body data indicating the spectrum of the reference body to become a reference at the time when the spectrum of the measuring object is corrected. A spectrum converting device has reference body reflectivity data indicating the surface reflectivity of the reference body, and creates ambient light data indicating the spectrum of the ambient light, on the basis of the reference body reflectivity data and the reference body data. By using the ambient light data, the measuring object data is converted into measuring object reflectivity data indicating the surface reflectivity of the measuring object. On the basis of the measuring object reflectivity data, a discrimination device discriminates the measuring object. |
