Title: Method for detecting surface defect over steel plate
Inventor: PARK CHANG HYEON
IPC: G01N21/89
Filed: 1998-12-26
Abstract: PURPOSE: A method for detecting a surface defect over a steel plate is provided to include a noise element of a defect detector itself such as an illuminator, a camera and so on in a reference image and to automatically convert the parameter value of a defect detection method based on the quality of the steel plate. CONSTITUTION: A reference image is generated by averaging plural images, and an object image is generated by shooting a steel plate(51). A difference image is formed by outputting the difference between the object and the reference images, and the defect existence is judged based on the difference image. When there is no defect, the oldest image is removed, and an image without defect is added up. Then a new reference image is generated by averaging again. A consistent reference image is generated by generating a new reference image from the image without the defect even if the quality of the steel plate is changed. Thereby, an operator does not need to regulate the parameter to the defect detection method manually.
