Abstract:
1. A movable body spectrum measuring apparatus provided with a spectrum sensor mounted on a movable body, the spectrum sensor being capable of measuring wavelength information and light intensity information, the movable body spectrum measuring apparatus discriminating a measuring object around the movable body on the basis of spectrum data of observation light detected by the spectrum sensor, and comprising: a storing unit for storing therein, as dictionary data, the spectrum data including the wavelength information and the light intensity information about a plurality of predetermined measuring objects; and an arithmetic device for discriminating the measuring objects on the basis of a comparison computation for comparing the spectrum data of the observation light and the spectrum data stored in the storing unit, wherein the arithmetic device performs the comparison computation for comparing the spectrum data of the observation light and the spectrum data by referring to only a partial wavelength band of the spectrum data stored in the storing unit as the dictionary data, wherein the spectrum data stored in the storing unit, as the dictionary data, is divided into a plurality of wavelength regions, and wherein partial wavelength band of data is selected from the plurality of wavelength regions such that data of the partial wavelength band is less than the spectrum data detected by the spectrum sensor, and that the partial wavelength band of data is processed by the arithmetic device in real time.
