Abstract

Disclosed is a mover spectrum measuring apparatus (11), which is able to discriminate an object being measured highly precisely by the photographic data of a spectrum sensor and is able to process the photographic data in real time. The mover spectrum measuring apparatus (11) discriminates the object being measured on the basis of the spectrum data relating to the observation light detected by a spectrum sensor (14). The mover spectrum measuring apparatus (11) comprises a dictionary data storing unit (16) for storing the spectrum data containing the wavelength information and the optical intensity information of the object being measured, and a regulation information storing unit (18) for storing regulation information to regulate the wavelength information into partial wavelength information. The mover spectrum measuring apparatus (11) further comprises a discrimination level setting unit for setting selectively the regulation information corresponding to the discrimination level required of the object being measured, a restricting unit for restricting the spectrum data of the observation light to the spectrum data composed exclusively of the wavelength information regulated by the regulation information, and a discrimination unit for discriminating the object being measured on the basis of the comparison between the restricted spectrum data and the spectrum data of the dictionary data storing unit (16).

Description

technical field [0001] The present invention relates to a spectrum measurement device for a mobile body that identifies a measurement target based on spectral data of the measurement target measured by a spectrum sensor mounted on a vehicle, particularly a mobile body such as an automobile. Background technique [0002] In recent years, many vehicles such as automobiles are equipped with devices that assist the driver's driving or decision-making by recognizing the status of pedestrians, signals, etc., which dynamically change around the vehicle, as driving assistance devices. Furthermore, such devices often capture the status of signals or pedestrians with a CCD camera or the like, perform image processing on the captured image in real time to perform status recognition, and use the result of the recognition for the above-mentioned driving assistance and the like. However, in general, pedestrians have various shapes due to their size, orientation, and presence or absence of...
