The second and third illumination light sources are provided such that a second angle between an optical axis of the second illumination light source and the optical axis of the line sensor camera is substantially equal to a third angle between an optical axis of the third illumination light source and the optical axis of the line sensor camera, and the first illumination light source is provided such that a first angle between the optical axis of the line sensor camera and an optical axis of the first illumination light source is larger than the second angle. The arithmetic processing apparatus calculates information on a hue of the metallic body surface on the basis of a luminance value of the reflected light beam of the first illumination light beam and information on surface roughness of the metallic body on the basis of luminance values of the respective reflected light beams of the second and third illumination light beams.

摘要： In a method of inspecting a steel strip, at least one surface of the steel strip is illuminated and scanned by at least one camera so as to generate an image record that defines a two-dimensional image of the scanned surface. The image record is sent to an image processing unit, with the image processing unit subjecting the image record to the detection of defects and, upon detection of a surface defect, classifying the detected surface defect. The steel strip is magnetized and the magnetic flux leakage on the surface of the steel strip is detected by at least one magnetic field-sensitive flux leakage sensor in order to detect inhomogeneities in the interior of the steel strip, with the flux leakage sensor generating a flux leakage record that is sent to the image processing unit and that is subjected by the image processing unit to the detection of defects so as to identify inhomogeneities in the interior of the steel strip.

摘要： A surface inspection method for a steel sheet coated with a resin, includes irradiating the steel sheet with sheet-like light, which has been linearly polarized at a predetermined polarization angle, at an incidence angle different from Brewster's angle of the coating by a predetermined angle or greater; and imaging linearly-polarized light of a polarization angle of 0 degrees at an acceptance angle different from a regular reflection angle of incident light by a predetermined angle. Accordingly, it is not necessary to change the incidence angle and the acceptance angle depending on resin components and it is possible to inspect a substrate steel surface of the steel sheet highly accurately without observing abnormalities in the coating itself.

摘要： The invention relates to a method for recognizing surface characteristics of metallurgical products, especially continuously cast products and rolled products. According to said method, a defined section of the product surface (12, 12′) is irradiated by at least two radiation sources of different wavelengths, from different directions, and the irradiated surface section is optoelectronically detected. Three light sources (21, 22, 23) are oriented towards the product surface (12, 12′), as radiation sources, under the same angle (a), the positions thereof being in three planes (E1, E2, E3) forming a 120 DEG angle and being perpendicular to the product surface (12, 12′). In this way, instructive information about metallurgical products can be determined and stored in a very short space of time such that the products can be determined in a perfectly identified manner for the reprocessing, in terms of the surface quality or surface structure thereof.

摘要： The present invention has its objective to provide a defect classification apparatus which suppresses over-fitting and accurately classify the defect type of a defect. A defect classification apparatus is provided in which a data point indicating feature information of a defect to be classified having an unknown defect type is mapped to a point in a mapping space having a dimensional number higher than the number of features constituting the feature information, and the defect type of the defect to be classified is classified based on in which of two regions of defect type, which are formed by separating the mapping space by a decision boundary, the mapped point is located, wherein a discriminant function indicating the decision boundary is determined by adopting a weight which minimizes the sum of the classification error, which corresponds to the accuracy in classifying a training defect dataset, and a regularization term, which has a positive correlation with the dimensional number of the decision boundary, as the weight for each feature constituting the discriminant function.
