Spectrum measuring apparatus for mover

Abstract

Provided is a mover spectrum measuring apparatus capable of improving the discrimination precision of a measuring object on the basis of the observation data of a spectrum sensor mounted on a mover such as a vehicle. A measuring object (15) and a reference body (17) are irradiated with an ambient light (14). A spectrum acquiring device (11) acquires measuring object data (16) indicating the spectrum of the measuring object (15), and reference body data (18) indicating the spectrum of the reference body (17) to become a reference at the time when the spectrum of the measuring object (15) is corrected. A spectrum converting device (12) has reference body reflectivity data (24) indicating the surface reflectivity of the reference body (17), and creates ambient light data (19) indicating the spectrum of the ambient light (14), on the basis of the reference body reflectivity data (24) and the reference body data (18). By using the ambient light data (19), the measuring object data (16) is converted into measuring object reflectivity data (20) indicating the surface reflectivity of the measuring object (15). On the basis of the measuring object reflectivity data (20), a discrimination device (13) discriminates the measuring object (15).

Description

technical field [0001] The present invention relates to a spectrum measuring device for a moving body mounted on a moving body such as a vehicle, particularly an automobile, for measuring the spectrum of light received from a measuring object. Background technique [0002] In recent years, vehicles such as automobiles are frequently equipped with devices for assisting the driver's driving and decision-making by recognizing the states of pedestrians and traffic lights, etc., which are dynamically changing around the vehicle, as the driving assistance device. Moreover, many of such devices use a CCD camera or the like to photograph the states of traffic lights and pedestrians, and perform image processing on the photographed images in real time to recognize the state, and use the result of the recognition for the above-mentioned driving assistance, etc. However, in general, since the shape of pedestrians changes variously depending on the size, orientation, presence or absenc...

AI Technical Summary

Problems solved by technology

Therefore, the spectrum of the reflected light observed from the measurement object depends on the characteristics of the light irradiated on the measurement object in addition to the optical characteristics of the measurement object itself, and there is a high possibility that the recognition accuracy of the measurement object will be impaired.
