SPECTRUM MEASUREMENT DEVICE
First Claim
1. A spectrum measurement device for recognizing a measurement target based on a spectral data set of observed light detected by a spectral sensor capable of obtaining wavelength information and light intensity information, the spectrum measurement device comprising:
- a lighting device irradiating light, including a wavelength band exhibiting a high atmospheric absorption coefficient, to the measurement target; and
a measurement target recognition unit recognizing the measurement target through an arithmetic operation using a spectral data set of light observed from the measurement target irradiated at least with the light including the wavelength band exhibiting a high atmospheric absorption coefficient.

Abstract
A spectrum measurement device that recognizes objects to be measured on the basis of spectral data of observed light that is detected by a spectrum sensor capable of measuring wavelength information and light intensity information. The spectrum measurement device comprises a lighting device capable of projecting light that includes a wavelength region with a high atmospheric absorption index and recognizes the distance from a vehicle to an object to be measured through a computation that uses spectral data of observed light that is obtained from the object to be measured whereupon light of at least the wavelength region with the high atmospheric absorption index is projected.
