| 摘要 |
The invention relates to a method for detecting a defect on a surface of a molded part, in particular an injection-molded part made of plastic, wherein the surface of the molded part is optically measured and a measurement result is evaluated in an automated manner in order to detect a defect, where applicable. According to the invention, at least one two-dimensional image is taken of the molded part in the form of an intensity matrix having n times m pixels using a camera, whereupon the intensity matrix is optionally converted into a further matrix, whereupon the intensity matrix or optionally the further matrix is folded using at least one function describing a contrast perception characteristic and/or a resolving power of a human eye, whereupon with respect to a predetermined threshold value the matrix obtained in this manner is used to calculate whether an existing defect, where applicable, is recognized by a human eye. |
