Patent ID: 8755048

Claim:
A movable body spectrum measuring apparatus having a spectrum sensor mounted on a movable body, the spectrum sensor being capable of measuring wavelength information and light intensity information, and the movable body spectrum measuring apparatus discriminating a measuring object in the surroundings of the movable body based on spectrum data regarding an observation light detected by the spectrum sensor, the movable body spectrum measuring apparatus comprising: a first storing unit for storing, as dictionary data, spectrum data including wavelength information and light intensity information for a plurality of predetermined measuring objects; a second storing unit for storing limitation information for limiting wavelength information included in a wavelength region of the spectrum data regarding the observation light to a part of the wavelength information classified based on an attribute of the measuring object; a discrimination level setting unit for selectively setting limitation information corresponding to a required discrimination level of the measuring object from the limitation information stored in the second storing unit; a restricting unit for restricting the spectrum data regarding the observation light to spectrum data consisting of only the wavelength information limited based on the selectively set limitation information; and a discrimination unit for discriminating the measuring object based on comparison between the spectrum data restricted by the restricting unit and the spectrum data stored in the first storing unit.
