摘要： A subject discriminating apparatus discriminates a subject having an unevenness pattern on a surface of the subject. The subject discriminating apparatus includes: a transparent unit including a supporting surface supporting the subject; a light irradiation unit irradiating illumination light onto the surface of the subject through the transparent unit; an imaging unit imaging an imaging region including at least a part of the transparent unit, and generating image data; and a discrimination processing unit discriminating the subject, using the image data generated by the imaging unit. The discrimination processing unit discriminates the subject based on discrimination image data generated by correcting subject image data using correction image data. The subject image data is generated by imaging the imaging region in a state of the subject presenting in the imaging region. The correction image data is generated by imaging the imaging region free from the subject in the imaging region.
摘要翻译：对象辨别装置鉴别被检体的表面上具有不均匀图案的被检体。被摄体识别装置包括：透明单元，包括支撑被摄体的支撑表面; 光照射单元，通过透明单元将照明光照射到被摄体的表面上; 成像单元对包括所述透明单元的至少一部分的成像区域进行成像，并生成图像数据; 以及鉴别处理单元，使用由所述成像单元生成的图像数据来区分对象。鉴别处理单元基于使用校正图像数据校正被摄体图像数据而生成的识别图像数据来辨别被摄体。通过在成像区域中呈现的对象的状态对成像区域进行成像来生成被摄体图像数据。校正图像数据通过在成像区域中对与被摄体无关的成像区域成像而产生。

摘要： An imaging unit images a subject having an unevenness pattern on a surface. The imaging unit includes: a surface light source that emits with a constant output illumination light illuminating the surface of the subject; an imager that receives reflected light reflected by the surface of the subject; and a beam splitter that is arranged at a location at which the illumination light emitted from the surface light source and the reflected light incident on the imager intersect with each other. The illumination light emitted from the surface light source is incident on the surface of the subject via the beam splitter. The reflected light reflected by the surface of the subject is incident on the imager via the beam splitter. The illumination light incident on the surface of the subject includes parallel light that is perpendicularly incident on the surface of the subject, and diffused light.
